It's reported that a Chinese company has created a new facial recognition system that can identify (识别) people even if they are wearing masks. Developers began working on the new system in January 2020 when the novel coronavirus appeared in China. The fast spread of the virus has led most people to wear masks in public to protect themselves and people around.
China is regarded as a world leader in the development of artificial intelligence (AI). According to engineers at the Beijing——based Hanwang Technology Ltd, this system is the first to be created to identify people wearing face masks. A team of 20 engineers completed it in about a month, adding a collection of about 6 million unmasked faces and a smaller collection of masked faces," the company said.
Hanwang is now selling two main kinds of products using the new technology. One performs single channel recognition (单通道识别), which will be used at the entrances to buildings. The other product is a multi—channel (多通道识别) recognition system that uses groups of cameras. It's said thatthe multi—channel system can identify a person in a crowd of up to 30 people within a second.
When people wear a mask, the recognition rate can reach about 95 percent," said Huang Lei, Hanwang's vice president. The system's success rate for people without wearing a mask is about 99. 5 percent."
Nowadays the new system is trying to identify people with both sunglasses and a mask. In such cases, all of the key facial information is lost, making recognition hard," Huang said.

On May 27th, the national cultural office dropped management of vendors and other roadside businesses in the city as a requirement for deciding if ạ city can be given the civilized city" title. In less than a week, one city after another has introduced polices (政策) that will benefit (使受益 )vendors and a wide group of other people and will also raise the economy (经济).
The first to benefit are job—seekers. In Chengdu, capital of Sichuan Province, which is famous for its rich kinds of snacks, the policy created 100,000 new jobs overnight, and 100,000 households have got a better income.
Vendors do not have to spend money renting ( 租用) a place. All they need is a 2 square meters of space by the roadside for two to three hours in the evening. And all the money they make from it goes to them or their families. However, that does not mean common shops will lose customers. The two kinds of businesses are different parts of economy.
Office——goers too will benefit. Instead of having to wait in a long line at a supermarket, they can now snack from a vendor after a whole day in the office. They can appear from a subway station and grab a cake or get off a bus and buy some handmade ice—cream.
City management officials, or chengguan are also doing less stressful jobs now. Earlier, their job was to drive away vendors doing businesses without licenses. They are now more helpful, making sure that vendors are dealing with their garbage before shutting business for the day and looking for space for vendors at a place with no traffic problems or which won' t cause traffic problems.
But that will need more wisdom and more services to the people, which in turn requires the local governments' wisdom. Time for them to be creative!
