Knight armor catapult giant slingshot goes into battle in Kiev, Ukraine.

The street situation in Kiev, the capital of Ukraine, is getting out of control. Because the contradiction between the opposition and the government is difficult to reconcile, on the evening of January 22, protesters and police clashed bloody in the Independence Square in Kiev, the capital, killing five people and injuring more than 300 people. Witnesses said that four of them were shot and killed by the police, and the fire enveloped the whole city center. The scene was described as a "war blockbuster".

Ukraine has always been very strict in gun management. Proceeding from the principle of legal possession of guns and self-defense, the Ukrainian Ministry of Internal Affairs has determined the principle that guns must be registered by the state, the principle of production license and the principle of bringing them into the country. It is forbidden to use silencers and accessories with night vision sights for official and civilian guns in Uzbekistan. The purchase of guns must hold a special license from the Ministry of Internal Affairs of Ukraine, valid for 3 years. Therefore, although both the demonstrators and the police used guns in the conflict, the police mainly used them to fire tear gas and rubber bullets to disperse the demonstrators, and the number of guns of the demonstrators was also very small. Most conflicts are caused by the use of sticks, shields and other weapons by both sides.

Street demonstrations in Ukraine have evolved into serious violent confrontations.

Street demonstrations in Ukraine have evolved into serious violent confrontations.

During the conflict, the Ukrainian police took strict organization, and a large number of policemen wearing full-body protective gear, helmets, shields and batons formed a "human wall" at the scene of the conflict to stop the violent actions of demonstrators. Not to be outdone, the opposition not only robbed many police weapons and equipment, but also "self-developed" many weapons similar to those of the ancient war against the police, which made this conflict take on many "medieval" colors.

shield

In the conflict, both sides used a large number of shields as formations to defend against all kinds of tear gas and fireworks thrown by opponents. Most of the demonstrators’ shields were seized from the Ukrainian police, and these shields were simply decorated and distinguished with paint. Of course, more so-called shields are mainly a board. At other times, however, a few carefully decorated shields also appeared at the demonstration site. These shields are larger in size, better in material and stronger.

A set of shields used by demonstrators in Kiev. They should be made of plexiglass and can be easily carried by demonstrators. The red cross and green background on the shield give people a sense of medieval war.

When the police fired tear gas, this group of demonstrators formed a tortoise shell array with great literacy to prevent the crowd from being dispersed by tear gas.

Another shield painted with the Red Cross looks like a crusader. A demonstrator is hiding behind a shield and firing a rocket at the police.

rocket

In response to the police’s use of tear gas, many demonstrators also fired a large number of fireworks for festivals. Many people lit fireworks from water pipes and fired them at the police, and combined with throwing stones and burning bottles, they tried to stop the police from expelling.

The rocket flying out of the steel pipe shows that the demonstrators with shields in front are facing the police against the barricade.

A demonstrator who is launching a rocket has a handful of "ammunition" waiting to be launched.

However, it would be a big mistake to think that rockets are the most advanced weapons of the opposition. In order to completely overwhelm the police, the opposition demonstrators also created several real "big guys".

 

 

Siege machine

At least one wooden trebuchet and a giant slingshot were assembled and used in demonstrations in Kiev, the capital of Ukraine, to shoot stones and other sundries at the police.

There are many curious demonstrators watching the trebuchet being assembled.

The trebuchet, which was completed at night, was planned by the demonstrators to throw all kinds of sundries at the police.

This is not a real-life version of "Angry Birds", but a demonstrator using a homemade giant slingshot to shoot stones at the police. Being hit by something like this is not fun at all.

Another huge slingshot, the demonstrators in front are trying to stabilize the support, while the people behind are shooting stones.

Demonstrators and bystanders

In addition to the large weapons on the scene, demonstrators also used various means to protect themselves. Helmets, goggles and thick coats are common equipment. What’s more, it also moved out the knight armor that may have been handed down from family.

Demonstrators armed with sticks and ready for battle can see that helmets, goggles and masks from all sources are standard.

The demonstrator even put on a knight’s armor from nowhere. Although it is not a complete set, it is definitely cool.

It is necessary for journalists who walk through the crowd on both sides to hold a bowl in order to prevent "accidental injury"

The key for Roewe to enter the state of "shopping" is autonomy.

If you have requirements for the power of the vehicle, besides the engine parameters, you should actually care about some other data. What I want to introduce to you today is. Let’s take you to appreciate its style.

First of all, from the appearance, the Roewe RX5 front gives people a very lovely feeling, and the China Net uses a multi-spoke shape, which makes people unforgettable. Combined with the front lights, the grade of the whole vehicle is improved. The car is equipped with LED daytime running lights, automatic opening and closing, adaptive far and near light, delayed closing and so on. Coming to the side of the car body, the size of the car body is 4655 mm * 1890 mm * 1664 mm. The car adopts simple lines, and the car body looks very simple. With large-sized thick-walled tires, it looks full of sports. In the design of the rear end, the rear end looks sharp, the taillights look domineering, and with the unique exhaust pipe, the shape is simple.

Sitting in the car, the interior design of Roewe RX5 is very stable, giving people a very dignified feeling. The steering wheel of the car is very in line with the interior style, and it is made of genuine leather, which looks a little more simple. Let’s take a look at the central control, with a 27-inch central control screen, which makes the interior style impressive and has a certain sense of science and technology. Next, let Xiaobian introduce the dashboard and seats. The dashboard of the car presents a simple design style and the shape takes the sports route. The car adopts leather seats, equipped with functions such as electric adjustment of auxiliary seats, electric adjustment of seats with memory, and seat proportion tilting, and the comfort is acceptable.

Roewe RX5 is matched with a wet dual clutch (DCT) gearbox, with a maximum power of 138KW and a maximum torque of 300N.m, with good power performance.

In terms of configuration, Roewe RX5 is equipped with car networking, driving mode selection, remote control key, Bluetooth key, rear wiper, interior atmosphere light and other configurations.

This car has been introduced almost before, and I believe many users who buy a car have taken a fancy to its comfort and practicality. If you have plans to buy a car now, then today’s car is worth learning about.

The exposure of the profiteering chain of waste oil has a net profit of 3 billion per year.

  The Ministry of Public Security cracked a major case of "gutter oil", and the official officially confirmed that "gutter oil" flowed to the table. This incident has once again stung the public’s nerves by the hidden worry of "gutter oil" that has been silent for a long time. After more than a month’s investigation, the reporter of China Business News found that "gutter oil" is flooding in China. First, due to the temptation of profiteering in the whole production and sales chain, the annual net profit is 3 billion yuan, which is equivalent to a central enterprise under the State-owned Assets Supervision and Administration Commission. Second, it is due to the lack of supervision by government departments. "Waste oil" is so rampant, where are the government departments such as industry and commerce, quality inspection, urban management, health and epidemic prevention?

  Famous catering enterprises and universities become "oil sources"


  Recently, the Ministry of Public Security cracked a major case of "gutter oil", which once again aroused people’s concern about "gutter oil". Prior to this, the reporter of China Business News conducted a one-month investigation and found out the whole "gutter oil" industrial chain. Under the temptation of high profits, "gutter oil" has formed a huge industry.


  The huge profits behind the price difference in 0.2 yuan


  "We can’t invoice the oil here. It’s almost 185 yuan a barrel, about 40 pounds, and the good one is 205 yuan a barrel. If the temperature is low, it will crystallize, but the good one will not." At the farmer’s market of Nanliangjia Store, Beiqing Road, Changping District, Beijing, a shop assistant pointed to more than 20 white plastic vats under the porch.


  "How can you not invoice? It’s only 4 yuan and 6 pounds. I bought it in the unit canteen. I’m afraid it’s’ gutter oil’. Can you give me a certificate of conformity? "


  "yes." The man answered and handed over a copy paper, which was an edible oil inspection report of a company in Tianjin. It was stamped with the official seal of the inspection agency and impressively printed with the acid value below 1 (acid value below 1 is the first-class edible oil standard). "I will give you as much as you want."


  Such a scene is staged in the farmers’ market around the city every day, and the edible oil refined from "gutter oil" is rampant. In the farmer’s market near Liangjiadian, Beiqing Road, Beijing, we can see that there are countless small vendors selling "gutter oil" in dozens and hundreds of barrels.


  "I have been checked once, but it has been loose in recent months and can be sold again." A store owner described this. Colleagues told reporters not to take pictures, otherwise it will lead to danger, because almost every shop here does such business.


  According to people in the market, a barrel of 40 Jin on the surface actually weighs only 37 Jin, so the price of a Jin is 5 yuan money, and a better Jin of 5.5 yuan. The cheapest price of soybean oil in the supermarket is 5.7 yuan, which is 6 cents or even 20 cents cheaper, which is similar to the price of soybean oil.


  Previously, some professionals questioned whether the "gutter oil" could be returned to the dining table, on the grounds that it was difficult to remove the rancidity and odor of the "gutter oil" itself by simple means, and if it was deeply processed, the cost would be high. In this regard, Chang Hai, a researcher at caams Institute of Oils and Fats, said that it is not difficult to extract edible oil with "waste oil", and the cost is very low, so a small enterprise can do it. "Some media said that the cost of refining is not more than one ton in 300 yuan. I have not studied it carefully, but it will certainly not be too expensive."


  So, is it more likely that a catty of 0.6 yuan oil is cheaper than 0.2? Is it "gutter oil" or soybean oil? Xiang Hai didn’t give a positive answer, but he explained: "Edible oil production is an extremely mature industry, and the competition is fierce. Don’t say that 60 cents a catty is 20 cents cheaper, and oil dealers will break their heads for it. Think about it, a catty is 20 cents cheaper, one ton is 400 yuan, and the oil sellers are tens of tons and hundreds of tons of wholesale. A batch can earn tens of thousands or even hundreds of thousands of yuan! "


  Famous restaurants become "gutter oil" and "upstream"


  Since oil from illegal channels is flooding in large quantities, where does all this oil come from? In a restaurant, the reporter interviewed a person who has been digging for "gutter oil" for ten years: "Our favorite restaurants are those that use more oil, such as brand Hunan restaurant and brand Sichuan restaurant, which are the places with the largest amount of gutter oil." While eating, the person pointed to the dish and said with a smile, "I don’t want to order oily dishes when I eat in a restaurant, such as boiled fish, boiled meat, or even Mapo tofu and eggplant braised in oil. How many stores will use oil well?"


  Under the introduction of this person, the reporter went to a famous brand restaurant in Beijing to "squat". At 90 o’clock in the evening, a minibus arrived at the restaurant on time, and the oil dealer who got off the bus looked around warily first. After all, the wind is tight now, and those who illegally pay for oil are afraid of an accident.


  However, the store obviously had an agreement with him. The oil digger cleaned up the kitchen garbage first, and then took out a long pole from the car with a helmet-like spoon tied to his head. He began to open the manhole cover marked "dirty" and dig out the oil floating on the upper floor in the grease trap of the hotel. About seven or eight minutes later, he finished his work quickly, put the bamboo pole away, carried the oil drum back to the car, and drove to the next working point.


  The reporter investigated catering enterprises in Beijing, and found that many catering enterprises, including some famous brands, such as South Beauty, Hunan and Hubei Love, Guo Lin Home Cooking, etc., all gave kitchen waste and "gutter oil" to some unqualified individual collectors for collection. The key point is that although these catering groups are very large, they seldom pay attention to the treatment of "gutter oil" and never sign a unified recycling agreement with recycling enterprises. The recycling of "gutter oil" is decided by each store. In the South Beauty Store in Zhongguancun, Beijing, the Guo Lin Store in the South Road of Beijing Academy of Sciences, and the Xiang ‘eqing Store in the south of Anhua Bridge in Beijing, reporters found that the oil collectors who came to collect oil at night had no legal qualification.


  According to the regulations, Beijing should not allow trucks to enter the Fifth Ring Road until 11 pm. "The police don’t care about oil dealers," said an industry source. "There are two reasons. The first is that they can’t pay much, and people have no money; The second is that even if you impound his car, where will you put it? It stinks, and when you put it in the station, your colleagues will scold you! " This person’s words highlight the fact of the "gutter oil" industry-there is a law but there is no way to take it.


  Colleges and universities are an important source


  Master Yang has been digging for "gutter oil" for many years. When he entered the gate of Peking University, he went straight to the Nongyuan Restaurant. There is a dirty manhole cover at the back of the restaurant. He skillfully buckled the hole in the manhole cover, gently pulled it open and took a look inside.


  "Just finished, the oil has already left." He said.


  The liquid under the manhole cover has been empty, and disgusting leaves are floating. In many places, Master Yang almost doesn’t need to open the manhole cover. As long as he looks at the manhole cover, he will know if anyone has been here. This is the "sense of smell" that has been cultivated for many years.


  "Just a Peking University Agricultural Park, you can get 200 kilograms of hogwash fat every day." Master Yang couldn’t talk about the business of Peking University, but he knew exactly where the important oil source was, and his words showed envy. A person from the catering department of Peking University said that in the normal school season, there are 50,000 people eating here every day, and the consumption of three meals a day is amazing.


  "Peking University’s farm garden and spoon garden, these restaurants are all talked about, and they can get 400 kilograms to 500 kilograms of’ ditch oil’ a day." Master Yang said that big restaurants should pay twice a day, and small restaurants can do it once. After one year, a Peking University can make you at least 200,000 yuan, and "Tsinghua is similar".


  In Tsinghua, near Peking University, there are 40,000 people dining, and there are 24 canteens in total. Oil diggers know this like the back of their hands. Because if you can package it, you can pay hundreds of barrels of oil a year (more than 100 kilograms of oil per barrel), including vegetable oil (fried oil, about several hundred kilograms) that can be sold at a higher price, which is an absolute considerable income.


  "Beijing is a place where colleges and universities are densely populated. Hundreds of thousands of college students, plus hundreds of thousands of students who are studying, have a very large amount of kitchen waste, including gutter oil," said a person in the gutter oil industry. "If gutter oil is to be treated, colleges and universities should definitely be the first to be treated, because colleges and universities have catering centers to operate, and it is generally easier to manage by agreeing on a recycling company."


  Master Yang estimated that universities should account for more than 10% of the "gutter oil" market in Beijing. Secondly, there are troops, large institutions in Beijing, large hospitals, etc., and their consumption of catering oil is no less than that of large catering enterprises.


  On the surface, there is no need to pay for the recycling of "gutter oil" and kitchen waste in colleges and universities, but in fact, there are hidden rules. As far as the reporter knows, at present, the recycling of "gutter oil" in universities such as Peking University, Tsinghua, People’s Congress and Institute of Technology is carried out by enterprises that have not obtained formal qualifications. According to industry insiders, the entry threshold of some universities, including the most famous universities in China, is around tens of thousands of yuan every year. When interviewed by several universities, none of them gave a positive answer to this question.


  This is just Beijing. The resident population in Beijing is only 16 million, and there are more than 30,000 employees engaged in the "gutter oil" industry in China, with an annual net profit of more than 3 billion yuan. This scale index is no less than that of a central enterprise under the State-owned Assets Supervision and Administration Commission.


  process


  Camouflage of processing plant


  In the case of "gutter oil" uncovered by the Ministry of Public Security, a company named wesen Energy Co., Ltd. (hereinafter referred to as wesen) came into public view. Recently, a reporter from China Business News went to the location of this company to investigate and found that the existence of an enterprise that manufactures and sells "gutter oil" like wesen is related to the lack of supervision.


  Camouflage of "chemical enterprise"


  "For the serious violations of Jinan wesen Energy Co., Ltd., neither the people nor the village cadres in the village know, and we usually have no chance to get close to the company’s factory building. When they came in under the guise of developing biodiesel, they didn’t have to say hello to us at all. We only knew that biodiesel was produced. " Yang Xinggang, Diaoshanpo Village, Pingyin County, Shandong Province, told reporters frankly.


  The reporter interviewed several villagers in Diaoshanpo Village. Many villagers said that they didn’t know what this enterprise was doing until the police arrested Liu Liguo, the person in charge of wesen.


  Diaoshanpo Town is a chemical town, with five series of leading products, including pesticides, dyes, pharmaceutical intermediates, refractories and catalysts, with an annual output value of more than 200 million yuan. Chemical industry has become a characteristic leading industry and one of the economic pillars of Diaoshanpo Town. Therefore, the emergence of wesen, in the eyes of most people, is just another chemical enterprise in Diaoshanpo Town.


  Liu Liguo chose the refinery in the most sparsely populated place in the northwest of Diaoshanpo Village. The site used to belong to the seat of Diaoshanpo town government, and the land and factory buildings are state-owned, and the site of Mei Shuikou Co., Ltd. on the south side of it also belongs to the government land. Its west and north are farmland, and the processing factory in the east is separated by an asphalt road. In Yang Xinggang’s words, this site already belonged to state-owned land in the early 1990s, during which several factories were changed and built here. All taxes were owned by Pingyin Local Taxation Bureau, and it did not involve occupying villagers’ cultivated land, so it was naturally difficult to attract villagers’ attention.


  Although the factory is located in Diaoshanpo, it has nothing to do with Diaoshanpo. Because the factory is heavily guarded at ordinary times, there are barbed wire and cameras around the factory, and villagers are generally afraid to get close.


  In order to keep secret, most of the employees employed by the refinery are foreigners. The factory has also made strict regulations on the employees in the factory. All employees must be approved by the company leaders before entering the factory. The employees of the company are forbidden to bring outsiders, including family members, into the factory and talk to strangers, otherwise they will be fined.


  According to a villager, one of his relatives worked in it for more than two months, and the salary offered by Green Company to employees was as high as 3,000 yuan, which is a "high salary" in the local area where agricultural income is the mainstay. However, the employee only worked in it for more than two months and really put up with the smell inside and quit.


  Regulatory vacuum


  The reporter learned from the information obtained by Pingyin Branch of Jinan Administration for Industry and Commerce that wesen Energy Company was established on June 7, 2010 with a registered capital of 1 million yuan, and its business scope covers the production and sales of biodiesel (fatty acid methyl ester), oleic acid, stearic acid and fatty acid.


  Wesen has existed in the name of biodiesel for more than a year, and no government supervision department has supervised it. In this regard, the reporter interviewed the local industrial and commercial bureau and the Bureau of Quality and Technical Supervision.


  "wesen Energy Co., Ltd. turned to produce edible oil in the name of producing biodiesel, which is a kind of fraud. Our Administration for Industry and Commerce can only be responsible for the management of commodity quality and food safety in the circulation field and circulation links within its jurisdiction. " Zhang Yuhe, deputy director of Pingyin Industrial and Commercial Branch, explained this.


  Zhang Jianhua, deputy director of Pingyin Branch of Jinan Municipal Bureau of Quality and Technical Supervision, explained, "According to the Product Quality Law, the responsibility of the Quality Inspection Bureau is to carry out sampling supervision and inspection on certification products. Biodiesel is not a mandatory management product, so it is not included in the inspection. "


  Under the regulatory vacuum, wesen "sells dog meat by hanging sheep’s head". It is understood that wesen buys "gutter oil" from Huang Qiang, Zhejiang, Sichuan, Jiangsu, Guizhou and other places at a price of about 5,600 yuan per ton, and then processes it into edible oil and sells it at a price of about 8,300 yuan per ton. In the jargon of waste cooking oil processing, the waste cooking oil stored in the yard is called crude oil. If this oil is to be made into edible oil, it must go through at least three processes of hydrolysis, distillation and splitting, and finally the remaining oil is called red oil, which finally flows into the market. The amount of "red oil" produced by "gutter oil" is amazing. It is understood that wesen’s output reaches dozens of tons per day.


  Yang Feng, a long-term owner of grain and oil sales in Diaoshanpo Village, told reporters that in fact, if these oils are used as edible oil, they are particularly easy to distinguish. You can know which is "gutter oil" and which is normal edible oil by smelling it. Under normal channels, the relevant departments can know the sales target of oil as long as they regularly check the sales invoices of "waste oil" processing enterprises.


  The reporter’s investigation found that many local people did not believe that Liu Liguo, who was arrested, was the mastermind of the deep processing of "gutter oil". According to the announcement issued by wesen on June 28th, 2010, Jinan wesen Energy Co., Ltd. has an annual output of 40,000 tons of biodiesel, 10,000 tons of oleic acid and 10,000 tons of stearin. According to the announcement, the person in charge of the company is Zhong Chonggen, who has never appeared since the incident.


  In addition, the corporate name of Green Company found by the reporter on industrial and commercial registration information is Yu Qingpeng, and this person has never appeared, and the reporter has not got in touch with him through various means.


  According to the EIA of Shandong Academy of Sciences, the total investment of wesen project is 45 million yuan, and the annual profit after the project is completed is 15,748,400 yuan. But in fact, this enterprise has turned into a "gutter oil" factory. It is still a mystery how this transformation can be concealed.


  place/territory under sb’s control


  Division of forces of "gutter oil"


  "Waste oil", a seemingly disdainful occupation, contains huge wealth.


  "You don’t know this industry. There are many people who have made a fortune in this industry." Master Yang, who has been digging for "gutter oil" for many years, fiddled with the Apple iPhone4 mobile phone that he had bought for several months, giving an example of his family history. One started this business in the early 1990s, and now he has money. He bought several houses in Yizhuang, Beijing, and his son did nothing, so he went to take drugs and was arrested. The boss bought 50 acres of land in Beijing and even built a school at his own expense. Another boss, who started this business in 1991 and 1992, also made money. Now he has successfully extended his model to other places, and is building chains in other provinces to establish his own "gutter oil" kingdom. Not long ago, the boss built a new factory in Tianjin.


  According to the reporter’s information, the "gutter oil" market in Beijing has been divided up by various forces from other places and divided into gangs. These gangs have their own relatively solid sites, especially in the outer suburbs of Beijing. For example, in Daxing District of Beijing, there are Yuan family, Ma brothers and Dou family from Anhui. In Mentougou, it is run by Cheng and Xu from Jiangsu, and in Fengtai District, it is run by Zhou, Shen and Wang from Jiangsu. In Chaoyang district, it is Tang’s, and in Fangshan, it is Cai’s.


  "The oil and water in Beijing’s gutter oil industry was no secret around 2000." Master Wei, a practitioner of "waste oil" in Haidian District, introduced that in 1997, Beijing Environmental Protection Bureau set up Beijing Environment and Development Company, saying that it was an enterprise of Beijing Environmental Protection Bureau, but it was actually contracted by a private boss. Relying on the background of the Environmental Protection Bureau, this enterprise has collected more than 200 people engaged in the "waste oil" business in Beijing, and established two centralized waste oil treatment stations in Chaoyang and Fengtai. The two treatment stations take the central axis road of Chang ‘an Street in Beijing as the dividing line, with Chaoyang responsible for the west of the central axis road and Fengtai responsible for the east of the central axis road. "Every year, the East and the West each pay 600,000 yuan to the Environmental Protection Bureau, and the boss makes a net profit of nearly 8 million yuan, which was really not a small sum at that time." A person familiar with the matter said.


  It was not until around 2003 that the company was dissolved by the Beijing Environmental Protection Bureau because of the conflict between the boss of Beijing Environmental Protection Bureau and Beijing Environmental Protection Bureau. It is reported that for this reason, the private boss started a lawsuit with the Beijing Environmental Protection Bureau, which ended unexpectedly in the failure of the Beijing Environmental Protection Bureau. Beijing’s "gutter oil" market is in a dogfight again, while Beijing Environmental Protection Bureau is forced to withdraw from the "gutter oil" supervision market.


  "However, for illegal operators, this does not mean that the profit in this market has decreased." An industry insider said. Lang Xianping, an economist, calculated that the price of edible oil in the market is 6000 yuan per ton, and the cost of "gutter oil" is probably 300 yuan, and the total profit of the whole "gutter oil" industry can reach 1.5 billion yuan to 2 billion yuan a year.


  According to the estimation of Beijing Municipal Appearance Management Committee, the current authority in charge of "gutter oil" in Beijing, the total amount of "gutter oil" to be treated in Beijing market is more than 25,000 tons every year. According to Lang Xianping, if the profit range of one ton of "gutter oil" is at least 5,000 yuan, the total profit of 25,000 tons will be more than 125 million yuan.

Old Houses and Old Houses in Chinese: Japanese Renovation Plan

Recently, MUJI held an event called "Joy City" on the 3rd floor of Shanghai.Compact Life in China"The exhibition. The objects on display include modular cabinets of Muji, and daily groceries such as acrylic storage boxes, and the three "homes" that attract the most attention — — They are all decorated and arranged by muji products from the inside out.

These "homes" are actually the result of the transformation of three ordinary homes in Shanghai by the MUJI team. Each home has experienced a change from "dirty, chaotic and poor" to neat, simple and comfortable. These changes were recorded as short videos by time-lapse photography and played circularly at the exhibition site. In addition, the finished products were restored to the scene at 1: 1.

Previously, MUJI had done similar renovations and exhibitions in Japan, Taiwan, China and Hongkong, with the aim of promoting its modular furniture through the concept of "Compact Life" — — But aside from this, the exhibition still gives a lot of inspiration about home design, especially the renovation of old houses.

"This clean and bright Japanese style, compared with the previous renovation of the husband’s room, really makes people have the desire to modify their own homes." Just finished visiting.Compact Life in ChinaThe audience of the exhibition, Chi Cheng, told the interface reporter.

When it comes to the renovation of old houses, many people may think of a variety show called Dream Renovator. More than a year ago, this program caused a heated discussion by virtue of the strong contrast before and after the house renovation and various dramatic conflicts and turning points during the renovation process. Among them, the episode of Shuhei Aoyama, a Japanese architect, transforming Beijing quadrangles was the most popular.

The reason is: firstly, the program group crowned this quadrangle transformed by Shuhei Aoyama with the title of "the smallest school district in history", which increased the audience’s expectation for the transformation, and also made the contrast between the transformed "Japanese-style residence" and the quadrangle before the transformation stronger; On the other hand, Shuhei Aoyama’s Japanese identity also makes the whole case more concerned.

"I like his style very much. I wish he were not Japanese." The netizen "dreams point to the south" said in a reply to the related post of "Dream Renovator" in Baidu Post Bar. This represents a voice: Japanese people working in China, especially those projects such as rebuilding old houses in China, will be more or less affected by some negative feelings from China people towards Japan.

But more often, Japanese designers are very popular in the market of renovation and renovation of old buildings in China — — A little search on the Internet will reveal that it is no exaggeration to describe the condition of Japanese designers’ renovation of old houses in China by "getting together".

In addition to Shuhei Aoyama and the MUJI team, world-renowned architects Kengo Kuma and Fujimoto Shosuke were invited to renovate the old quadrangle in Beijing. One of them made a Zen teahouse, and the other rebuilt the Beijing Humanities and Art Center. You may have heard of a Japanese architectural firm called odd, which renovated six or seven hutong houses in one breath in Beijing. In another program of Dream Renovater, Japanese designer Ben Shi’s attempt to renovate a husband’s house in Shanghai is estimated to have impressed many people.

These cases have one thing in common, that is, the area of the space to be renovated is not large, and it can even be said that it is cramped, crowded and messy. I don’t need to go into details about those quadrangles and hutongs. Most of the time, a room of more than ten square meters or even smaller has to accommodate at least five people and their sundries. Similarly, MUJI has also selected old houses built in the 1990s in Shanghai, with an area of about 40 to 50 square meters.

"Houses with renovation needs generally have the problem of small area, which is the same in Shanghai and Hong Kong, including Tokyo." Gu Benzhan, director of the planning and design office of MUJI’s life and groceries department, told the interface news, "Metropolis is a place where people gather. After more people gather, the natural living space and the area that can be effectively used will become smaller and smaller."

Therefore, the advantages of Japanese designers are highlighted here. In an interview with Tencent Home, Shuhei Aoyama once said that many Chinese believe that Japanese designers are better at renovation because they "think that Japanese designers can make good use of small space and design better details".

In recent ten years, the aging problem in Japan has become increasingly serious, the population has been decreasing, and there are more and more empty houses, which has prompted architects and designers to shift their attention from building new houses to transforming old ones. A good example is the group land reconstruction project of MUJI in cooperation with Japanese urban institution UR. At that time, Muji’s team of designers transformed a group of "low-rent houses" that were gradually vacant in Japan after World War II into rental houses that met the preferences of young people, making those old houses that were supposed to be eliminated by the times have the meaning of existence again.

In fact, not only architects and designers, but also Japanese people have a lot of experience on how to make effective use of small space. This is largely because Japan has a small land and a large population, and it is popular to live alone. The family size is usually small, so the area of its own house is usually small. However, after experiencing the consumption era in 1980s and 1990s, Japanese people generally have a lot of things at home, which need to be accommodated — — This is why there are all kinds of strange but brain-opening storage techniques and storage tools for sale in Japan.

The process of urbanization and aging in Japan is earlier than that in China. What Japan faced in the past two or three decades is exactly what China is experiencing now.

Since 2000, the urban commercial housing in China has been growing by spurt, which makes the old husbands’ houses that were built and distributed in a unified way and the quadrangles and foreign buildings that have been passed down instantly become anachronistic, and they no longer meet the requirements of the times in terms of apartment type and community facilities. At the same time, the continuous relocation of industrial facilities to the suburbs has also left a large number of almost abandoned old buildings in the city — — Many of these buildings have been demolished, while the remaining buildings, especially those with historical significance or cultural heritage value, are waiting for renovation.

There has been a wave of transformation in the construction industry. Ma Yansong and many other buildings have tried to rebuild the hutong houses in Beijing. In the past two years, Beijing Design Week has been actively carrying out activities around the protection and reconstruction of traditional buildings such as old factories and quadrangles. Naturally, Japanese architects living in China have also caught up with this fashion, and their advantage is the skills and experience accumulated in their hometown.

"There are a large number of old houses with cultural and historical background all over China. After a period of newly developed construction, everyone returned to pay attention to the transformation of old houses, and reappearing the splendor of old buildings is the normal national development order. " Kooo architects Xiao Yan Shen and Xiao Yan Ayaka also told the interface news.

Xiao Yan Shen and Xiao Yan Ayaka recently completed a homestay renovation project in Yuhang District, Hangzhou, Zhejiang. They transformed a multi-storey residential building with China rural characteristics into a water town hotel with white walls and black tiles, making the building return to the appearance of an "ancient house" that is more compatible with the surrounding environment surrounded by green mountains and trees, but does not lose the sense of modern design.

Converting old houses into commercial public buildings is a common means to protect and reuse traditional buildings. The transformation of the whole tourist area of some blocks in Kyoto, Japan is typical. Many places in China have made similar attempts. For example, tourist areas such as Wuzhen and Xitang in Zhejiang, private restaurants in Beijing Hutong and Shanghai Alley, and creative parks in factories such as 798 and 751.

However, similar transformation can easily only stay in the building itself, protecting the formal tradition. Kyoto actually provides a more referential idea, because in addition to retaining the appearance of traditional Japanese-style buildings, the lifestyle and state of Kyoto residents can also be continued and preserved during the transformation process. This state of coexistence and interaction between people and buildings is the most attractive place in Kyoto.

"I think it is wrong to do only formal transformation. I hope that architectural transformation can preserve life itself." Shuhei Aoyama said, "And according to the demand, there are still more houses that need to be rebuilt, because many houses in China are mass-produced when they are designed, without considering the preferences of personal life. Now more and more people want to consider themselves, but they can’t find the right person."

Whether for public use or private residence, the rising demand for housing renovation in China provides more opportunities for Japanese architects and designers who are not dominant in their hometown. However, in comparison, the renovation of residential buildings like Muji and Shuhei Aoyama’s Dream Renovater needs to keep its practical use in life, and it faces greater difficulties, but the impact of the harvest is not as good as that of public projects, so there are not many people who really undertake this kind of civil housing renovation cases in their lives.

The house is for residential purposes, and the renovation will directly affect the lives of the residents, so (designers and teams) have little freedom to play. "Gu Benzhan said that this is the most difficult place in the whole Compact Life transformation.

Shuhei Aoyama’s experience in The Dreamer is the best example of this sentence of Gu Benzhan — — He first had a long and repeated communication with the owner in the program, and fully listened to the needs of the owner. In addition, because the reconstructed house is located in the quadrangle, and there are many public spaces, he also needs to communicate with his neighbors for many rounds. For example, the procedures such as opening the door and opening the window need the consent of the neighbors. However, after the renovation, the design results were still "destroyed", because the owners and neighbors still chose to use the new space in the way of "grounding gas" before the renovation.

This result is actually unexpected. In the face of the owners who have no storage habits before, the transformation of designers with "storage" as the core can only be a wishful effort in the long run. This will be a common phenomenon in China. From this perspective, Japanese designers who are good at making better use of small space through accommodation may not really meet the needs of a large part of China owners. And it is hard to say that such a transformation is good. Several Japanese designers interviewed by us all said that it is desirable to respect the lifestyle of the owners and not impose the wishes of the designers.

Many times, Japanese architects and designers will encounter obstacles from social development and ideological differences.

"Japan did not have the Internet as it does now in the early years of economic development. Therefore, I think that China’s rapid development was influenced by overseas more than that of Japan at that time. At present, the concept of Party A we contact is a very international concept. " The little couple said.

The most obvious manifestation of "internationalization" is that Chinese’s perception of "permanence" may be closer to that of western countries. In the west, a permanent building refers to a stone house that will never be demolished. What it looks like when it is built determines what it looks like later. Chinese’s pursuit of architectural renovation and indoor renovation all want to follow a pattern, just like whether in quadrangles or water towns, when it comes to public renovation of traditional buildings, he always wants to refer to a pattern of filming costume dramas.

This makes Japanese architects and designers who advocate the goal of "permanence" through continuous renovation and reconstruction somewhat uncomfortable.

"Doing the past is not a tradition, but doing what is needed now is to create a tradition, and tradition is not a copy of the past," Shuhei Aoyama explained by taking the work of Japanese temple workers as an example. "Ise Shrine is one of the most important shrines in Japan. There are two plots in the courtyard. The house on the left ground was demolished and rebuilt, so the right one was used. Twenty years later, the right one was demolished, and then the left one was used. In this way, workers can learn at the age of 18, operate at the age of 38, take the lead at the age of 58, and participate in the rebirth of a building three or four times in their lives. Such workers also have continuity. "

For Japanese or other countries’ designers, it is not a difficult problem to transform the building itself. What is difficult is how to keep the original advantages and integrate them into the thinking of China residents.

Moon Jae in was paid by China’s mobile phone and decided to do something big just after returning to China.

  [Global Network reporter Yang Feifei Wei Yue] South Korean President Moon Jae in paid a four-day state visit to China from December 13th to 16th. He not only started diplomatic activities in China, tasted Chinese breakfast, but also experienced a mobile payment. On the 18th, just the second day after returning to China, Moon Jae in decided to rapidly innovate its public network and cancel the unnecessary security plug-in activeX in electronic transactions.

  South Korea’s "Central Daily News" reported on December 18th that Park Soo-hyun, spokesman of South Korea’s Presidential Palace Cheongwadae, said on the 18th that South Korean President Moon Jae in said that when using public networks, the goal should be to cancel some unnecessary plug-ins during installation procedures, and quickly change administrative procedures and improve relevant legal systems before 2018.

  It is reported that South Korea’s active X is a security program installed during electronic transaction settlement, but there have been criticisms that activeX has slowed down the transaction. Although active X has disappeared in other countries, 44 of the top 100 websites in Korea still use Active X.. Previously, in March 2014, when former South Korean President park geun-hye held a seminar on system reform in Cheongwadae, he said that the "Chien Yong Yi Coat" in the Korean drama "You from the Stars" caused a wave of buying in China, but it could not be bought because of active X, so the government needed to start the work of eliminating Active X.

  When Moon Jae in had breakfast at Yonghe Soymilk in Beijing, he really felt the necessity of canceling unnecessary plug-ins.

  Moon Jae in scanned the QR code on the table for settlement after ordering. At that time, Moon Jae in showed interest in China’s mobile phone checkout system and asked, "Is this enough to pay the money?" Lu Yingmin, the South Korean ambassador to China, also said that "most of China uses mobile phones to settle accounts."

  This is not the first time that foreign leaders have been "circled" by China’s mobile payment.

  We are like "hillbillies"!

  On August 20th, the Straits Times published an article entitled "2017 National Day Mass Meeting: When lim swee say felt like a" hillbilly "in the smart city of Shanghai".

  At the beginning, the article tells the story of Singapore’s Minister of Manpower Lin Ruisheng buying chestnuts in Shanghai a few years ago. A few years ago, lim swee say saw people queuing up to buy chestnuts. They just shook their mobile phones and left without paying cash. Lim swee say thought it was a special discount, so when it was his turn, he told the vendor that I didn’t need a discount, and I would pay the full price. But the result is that people are using WeChat to pay for scanning the QR code of vendors. Mr. Lin feels like a hillbilly.

  The person who tells this story is none other than Singapore Prime Minister Lee Hsien Loong.

  Lee Hsien Loong used this story to tell Singaporeans that Singapore’s development has fallen behind some smart cities in China. In terms of electronic payment, China has been at the forefront.

  Lee Hsien Loong said, so when China tourists find it necessary to use cash in Singapore, they will ask, "Why is Singapore so backward?" Therefore, Singapore also plans to build a smart country to enhance the overall economic productivity and make life more convenient. Lee Hsien Loong said that all kinds of systems in Singapore must be simplified and integrated, and the relevant financial management departments have already begun to implement them.

  China Mobile Payment has long caused envy among many foreigners.

  In fact, the development of mobile payment not only in Singapore but also in China has long aroused the envy of many foreigners.

  In February this year, the Financial Times published an article entitled "Compared with China, the mobile payment market in the United States looks like a dwarf". Forrester described the payment scene in the United States in his report: "Old habits are hard to disappear. In front of the checkout counter, people are still more willing to take out their credit cards instead of taking out their mobile phones to sweep them."

  "China’s rapid push for near-end payment is largely based on its late-comer advantage — — Unlike the United States and other countries and regions, China does not have a solid credit card culture. It is precisely because of this that China has jumped directly from the cash payment stage to the mobile payment stage, "market research institute eMarketer said in a research report.

  After experiencing mobile payment in China, many foreign netizens said that it was very easy to use!

  Netizen: Although WeChat started as a communication application, it has now integrated the functions of 15 applications, which is very powerful. In China, you don’t need a wallet at all, just a mobile phone. You can buy anything anytime and anywhere by scanning the code. You can check your salary, make friends, call a car, send files, and do anything.

  User Jasmine HR: Is no one shocked by mobile payment? In China, you can buy anything as long as you have a mobile phone. You don’t need cash at all. Even if you buy a roadside stall, you can use your mobile phone for only half a cent. China is the first country in Asia to open Apple Payment, but Apple Payment is still not popular in China. Because China’s Alipay is so convenient, its function is more powerful than Apple’s payment.

  Do you think China is the most successful country in mobile payment?

  Netizen Vital Khali: It must be! So far, China is the country with the strongest mobile payment, and there is no one. In China, mobile payment has become a part of people’s lives: transferring money, shopping, eating, watching movies, paying rent and paying bills. Only unexpected things can’t be done without mobile payment. (Global Network Comprehensive China Journal, Singapore Straits Times, etc.)

The construction site became a "nightmare" for unmanned vehicles, and Google Waymo stumbled so much that he was interviewed.

Robotaxi, fire and theft prevention "construction site". Waymo fell.

The North American regulatory authorities have just opened an investigation into Waymo unmanned vehicles, because they received a series of related accident reports.

Some hit parked cars on the side of the road, some hit static obstacles, blocked traffic … and an unusual high-frequency scene:construction site.

In about three months, Waymo accumulated and reported 22 accidents, which attracted the attention of the National Highway Traffic Safety Administration.

According to NHTSA documents, these accidents include collisions between Waymo unmanned vehicles and static and semi-static objects (such as doors), collisions with parked vehicles and violations of traffic safety control devices.

Among them, the official special explanation of "violation of traffic safety control devices" is a key investigation direction, and a typical scene isAbility of automatic driving system to detect and identify traffic cones/ice cream cones.

This point is rare. Because many of the 22 accidents reported this time involve the same scene- construction site.

For example, last month,Waymo Robotaxi with 6 vehicles in formation.After work, I went back to the parking lot. As a result, I encountered temporary traffic control at the construction site and was directly stuck in the temporary traffic area surrounded by ice cream cones, causing traffic congestion for about half an hour.

Netizens with local life experience immediately recognized that this is the ramp at No.101 Potrero Avenue in San Francisco, where the Waymo unmanned vehicle was stuck, which happened to be the high-speed entrance.

Finally, it was the driver’s brother on the road who directly got off the driver to move the ice cream cone, and the team behind him bypassed several "paralyzed" unmanned vehicles in turn.

Waymo made a simple statement to the effect that people were sent to the scene to move the car within 30 minutes, without causing any casualties or property losses, and will cooperate with the investigation later.

But in the construction site of Phoenix, it is not so lucky.

The same Waymo unmanned vehicle ignored the construction area surrounded by the ice cream cone and rushed directly into the construction site.

Fortunately, the speed was not fast enough to hit people, but the vehicle itself and the construction site suffered losses to varying degrees.

There are many accidents like this. Every time an unmanned vehicle "rushes into the construction site", it will go viral on the Internet.

The netizen summed it up vividly:The traffic cone is Robotaxi’s kryptonite.Now, the miraculous automatic driving will be finished if it meets the traffic cone on the closed road.

Huh? It doesn’t seem to be the same as the video officially shown by Waymo.

Waymo The fifth generation autopilot system bypasses the construction area.It has been specifically analyzed as a technical highlight.

In the official Demo, the scene faced by unmanned vehicles is more complicated, except for traffic cones, irregular areas and workers walking back and forth.

Of course, the Waymo unmanned vehicle completed a series of evasive and detour actions effortlessly and successfully passed the construction area:

What is amazing here is that the Waymo unmanned vehicle seems to be able to understand the body language of human traffic command, let it stop and let it go, not just based on road conditions.

How did you do that? Maya Kabkab, the engineer in charge of the prediction algorithm of Waymo, briefly explained to the effect that in the fifth generation technology, Waymo strengthened the ability to understand different objects and targets and the ability to identify passable areas, which enabled the system to plan the passable route better.

The core is to replace CNN with a new model, VectorNet, to extract sensor and high-precision map information.

To put it simply, high-precision maps and sensor input information are represented as points, polygons or curves, while VectorNet represents all road features and trajectories of other objects as corresponding vectors. Based on this simplified view, VectorNet can extract the information of each vector and learn the relationship between different vectors.

The advantage is that VectorNet takes up less computing resources than CNN, produces results faster, and theoretically can extract key scene information more clearly.

But VectorNet still has no core to solve the "construction site" problem-

The "construction site" itself is an exception to high-precision maps.It is impossible to update synchronously, and it can only be sensed by sensors in real time.

However, the data of sensors are transmitted among different sub-models in turn, so it is difficult to completely avoid information loss.

Robotaxi is frequently stuck in the construction site, and the direct reason is the false detection of traffic cones and alien objects.

The underlying reason is thatThe upper limit and ceiling of the existing capacity of the traditional autonomous driving technology paradigmIt is difficult to cover all corner case on the road.

Therefore, whether the construction site can be avoided smoothly has become a probabilistic event: the official Demo has been carefully tested and repeated, which is no problem; If you only measure it on the road, you can only eat according to the weather.

"Never decide quantum mechanics when something happens" is a ridicule.

However, in the field of autonomous driving, if something is undecided, it is indeed possible to "end-to-end".

The so-called "end-to-end" is aimed at the traditional technology paradigm, in which the perception, decision-making, regulation and control of autonomous driving are independent of each other. The data collected by the sensor needs to pass through this series of different algorithm modules before it can finally become an operation instruction.

The information between each independent module is transmitted step by step. In this process, there will inevitably be information loss and errors, and the errors of the previous module will affect the next one, and the information errors between multiple modules will continue to accumulate, thus affecting the overall effect of the automatic driving scheme.

Whether it is pure visual perception or fusion perception, the root of "false detection and missed detection" is here.

Of course, there is also a corresponding solution, that is, through the rules of human handwriting, try to patch it to improve the reliability of perceptual recognition. For example, you can recognize cars and people, but you can’t recognize "people standing in front of cars". That’s easy. Why don’t you just build a separate data set for such targets and use it to train the model?

This is the so-called perceptual "white list" mechanism.

But the problem is that it is difficult to enumerate all kinds of traffic targets and scenes. This time, the problem of "people in front of the car" has been solved, but what if the car changes from a passenger car to a big truck? Or does a person become an adult and take care of children?

The same is true for Robotaxi’s construction site problem. The construction site may appear temporarily and refresh randomly, and it will not limit the area and time, and the construction and construction roadblocks of each construction site are different …

Therefore, a new algorithm paradigm-end-to-end algorithm model is needed to realize the lossless transmission of information from the beginning of perception and make the system truly understand the environment.

The two terminals refer to the data input terminal and the instruction output terminal respectively, and the middle is no longer divided into several independent modules.

The end-to-end model can transfer and generalize its learned abilities and skills to other scenes through a completely data-driven mode, independently and efficiently solve all kinds of new long tail problems in the berthing scene, have faster iterative efficiency and effectively reduce the cost of opening a city.

In layman’s terms, it is to let AI Division learn the mature driving behavior of human beings, see a scene and make corresponding countermeasures. In fact, "end-to-end" has touched the threshold of AGI.

In 2016, the end-to-end model was first proposed by NVIDIA. But the real mass production practice began in these two years. At present, only Tesla’s FSD and China’s AI players’ CVPR 2023 best papers-UniAD.

The Smart Car Reference also asked the opinions of the two domestic self-driving head players about the construction site problems encountered by Waymo.

Horizon from the perspective of engineering practice, think:

AutopilotSite problems and end-to-end technology paradigms are not bound.. Theoretically speaking, the problem can also be solved if the perception ability is strong enough and the perception white list is rich enough.

But obviously, end-to-end autonomous learning ability and humanoid thinking will solve this problem on a larger scale and more efficiently.

And Shang Tang’s view is more from the "first principle", and the relevant technical experts of Jueying Zhijia think:

Do not evaluate specific case. However, the perception of the traditional rule-based intelligent driving scheme still artificially defines the elements and abstracts the perceived information, which will lead to the loss and omission of the information transmission process and make it difficult for the perceptual decision-making module to make correct decisions. End-to-end is a neural network, which can input and transmit the information of the external environment without loss, understand the external traffic environment more accurately and completely, and make plans and decisions.

The rule scheme can solve a scenario by adding rules and patches. But there is not only one such scene, it is infinite. With enough data for learning and training, the end-to-end solution can think and drive like a human and solve more similar corner case by itself.

To sum up, Horizon and Shang Tang have different expressions, but the core is the same, and they all agree.End-to-end is the most effective way to solve Robotaxi site problems.. At the same time, it is the most efficient way to solve all kinds of long tail problems of autonomous driving.

By the way, I put forward UniAD’s CVPR 2023 best paper, which was written by scholars from Horizon and Shang Tang.

End-to-end innovation of traditional technology paradigm has given all players new opportunities: better intelligent driving experience, lower maintenance and generalization costs, and more competitive cost of autonomous driving scheme.

However, the price is the modular and rule-driven technical system in the past, which must be overthrown and reconstructed.

Waymo, the absolute leader of autonomous driving in the past, is now caught in the dilemma of "construction site", which further proves that the track of autonomous driving is "water is impermanent and soldiers are unpredictable":

Old stars may have their advantages reset to zero, and "latecomers" will also gain the lead.

Evaluation of Canon IXUS120 camera with 12.1 effective pixels

  Fashion elements permeate people’s hearts.


  I have to say that the shape design of card-type digital camera has completely marched into the fashion line. If it is not a fashionable design style to take out a card machine now, it is probably a product of several years ago. The IXUS series digital cameras released by Canon this year are the main color series, and the body is made of all-metal design with excellent texture. Different from the bright colors of the previous generation IXUS 100, the four colors used in IXUS 120 are "calm", namely cool silver, deep black, quiet blue and gorgeous brown.

  Canon IXUS 120 IS has further upgraded its performance while maintaining the slim design of the previous model. The optical zoom has been increased from 3 times to 4 times now, and a 28mm wide-angle end has been added. The lens focal length is equivalent to 28-112mm of a 35 mm camera, the maximum aperture is F2.8 (wide angle) /5.9 (telephoto), and the body thickness is 20mm (the thinnest part is 18.5 mm).

  Canon IXUS 120 IS LCD screen has a size of 2.7 inches, and adopts 12.1 effective pixel CCD and DIGIC 4 image processor. It supports the shooting of 720P HD video and provides users with an HDMI output interface. Based on the original 18 kinds of scene detection, the upgraded "intelligent automatic" mode adds 4 kinds of detection in moving scenes, with 22 automatic detection of detailed scenes and 22 kinds of color icon display.

  Stylish overall appearance


  Canon IXUS 120 IS body adopts all-metal matte design, which is not only fashionable in appearance, but also can effectively avoid fingerprint residue. Although the volume is only 89.5×54.9×20mm, the net weight of the fuselage reaches 120 grams, which makes it feel good in the hand and has excellent texture.

  Below the interface are the playback key and the shooting mode switching lever. The mode lever is divided into smart shooting, program shooting and camera shooting modes from top to bottom. Below them are five-dimensional directional buttons, which control the functions of exposure compensation, macro, flash mode and deletion/timing shooting respectively. The middle button has both the shortcut menu and the confirmation function. The bottom DISP. is the screen display button, and the MENU is the machine setting menu button.

  Large wide angle can not only shoot more elements in a limited range, but also have great advantages in reflecting large scenes. Canon IXUS 120 IS has no obvious image quality degradation around the wide-angle end, and the performance effect is good.

  Resolution and ISO represent moderation.


  In this evaluation, we tested the imaging resolution of Canon IXUS 120 IS in CBSi China Laboratory. We used the program automatic mode at the wide-angle and telephoto ends of the camera to shoot the ISO12233 resolution plate at the highest optimal image quality, and tested the final score by HYres software.


  At the same time, we also used the ISO of the camera to shoot the standard still stage to complete the sensitivity test. During the test, the author adopted the program automatic mode, automatic white balance and optimal highest quality shooting of Canon IXUS 120 IS camera, and intercepted the same area for comparison.

  Canon IXUS 120 IS shows obvious inherent problems of small cameras in resolution test-the difference between wide-angle end and telephoto end is obvious. The result of 2240 LW/PH at the wide-angle end has reached a high level, but we can find a slight dispersion phenomenon in the screenshot of the central area of the telephoto end. And in the actual shooting, it can be clearly felt that the effect of IXUS 120 IS wide-angle end is better than that of telephoto end.

  Canon IXUS 120 IS has a good image quality below ISO200. The camera not only has a good tolerance, but also has a pure picture. As the sensitivity rose to ISO400, IXUS 120 IS began to show its advantages over the previous products, and the photo quality was very close to the ISO200 of the previous camera. Although in ISO800 and ISO1600, the photo quality of Canon IXUS 120 IS still inevitably declined in an all-round way, but the photos did not appear mottled and color cast, and they still have certain usability after being reduced in size.

  Menu control is easy to use.


  Canon IXUS 120 IS menu design inherits the consistent design style of IXUS series. Simple and clear, each menu item has text for comments. Convenient for primary consumers to set up. First of all, let’s take a look at the interface display in its shooting state.

  We can see the shooting information from the LCD screen, such as the battery charge, the horizontal shooting direction of the camera below, the focus frame, the current shooting mode, the flash mode and the ISO value.


  We can clearly understand the various menu configurations of the camera through the above animation display. The overall parameter design is relatively simple and easy to understand, so we will not introduce it too much. The menu of Canon IXUS 120 IS can be easily mastered by consumers in less than 10 minutes, which is more user-friendly.

  Including the appreciation of the wide-angle proofs in front, and the indoor and outdoor proofs on this page, Canon IXUS 120 IS has excellent color reproduction and accurate automatic white balance. It has IS anti-shake ability, so it can basically ensure shooting with low sensitivity in a poorly lit room. Through observation, we found that when shooting Gao Fancha scene, Canon IXUS 120 IS will have slightly visible purple edge. The overall picture quality is maintained in a better range.


  Canon IXUS 120 IS adopts DIGIC 4 image processor, which can shoot high-definition video files with 1280×720 30 frames/second, and with 28mm lens, it can shoot excellent wide-angle video files. Let’s show you its shooting ability. Netizens can preview the video first, and then choose the video they are interested in to download and enjoy the original film.

  Evaluation summary


  Canon IXUS 120 IS is compact and stylish, with an all-metal body design and excellent feel. With a wide angle of 28mm, the performance is more outstanding. At the same time, it can shoot high-definition video at 1280×720 and 30 frames per second. The current market price of IXUS 120 IS in the early 2000 yuan. We believe that with the passage of time, the price of IXUS 120IS will be more cost-effective and will become one of the most competitive fashion card-type digital camera products in this price segment.


Malicious fee deduction, privacy theft … Attention! These 10 apps are "toxic"

  Xinhua News Agency, Tianjin, June 16 (Reporter Zhang Jianxin) The National Computer Virus Emergency Response Center recently found through Internet monitoring in the "Net 2019" special action that ten illegal and harmful mobile applications exist in the mobile application publishing platform, and their main hazards involve malicious fee deduction, privacy theft and gambling.

  These illegal and harmful mobile applications are as follows:

  1. Three mobile applications, Calendar (version 1.0), Avatar Bar (version 1.0) and Pictu (version 2.9.1), subscribe to various charging services without users’ knowledge or authorization, and have the property of malicious fee deduction.

  2. Ramadan Wallpapers (version 1.1), Charge and Sync Dock Reviews (version 1.0) and MayDayOnAir (version 2.0.6) obtain personal information of users without their knowledge or authorization, which has the property of privacy theft.

  3. Dehui Technology (version 1.2), Temi Technology (version 1.2), Tianhui Kindergarten Parents (version 1.2), and Competitive Happy Card — Boutique Games (Version 1.0) These four mobile applications are related to gambling, and gambling activities involving gambling funds are carried out in the form of betting points, playing cards and gambling, which is suspected of breaking the law and making users have property risks.

  In view of the above situation, the National Computer Virus Emergency Response Center reminds the majority of mobile phone users not to download these illegal and harmful mobile applications first to avoid unnecessary security threats to the mobile phone operating system. Secondly, it is suggested to turn on the "real-time monitoring" function of the anti-virus mobile application in the mobile phone to actively defend the operation of the mobile phone, so as to monitor the intrusion activities of unknown viruses in the first time.
