Central China's Zhengzhou, a city just recovering from devastating floods, has launched a third round of citywide nucleic acid testing to cope with the recent COVID-19 resurgence.

The city on Saturday started comprehensive testing in high- and medium-risk areas, which was expanded to the entire city on Sunday.

Tightened control

Zhengzhou added three residential compounds and one village to the list of medium-risk areas on Saturday.

The city announced it would introduce a closed-loop management system across the city from Friday to stop the risk of COVID-19 spreading. People living in high-risk areas are being asked to stay inside their compounds.

So, are the tighter restrictions causing panic among the population?

"I don't see it having too much influence," Liu Li, a shopper at a supermarket in Zhengzhou, told CGTN.

Liu does not live in a high- or medium-risk area. 

"We're free to go in and out of the place I live," said Liu.

"Small shops lack vegetables sometimes, but at supermarkets like this one, people can get whatever they want," she added.

Supermarket manager: Essential items for people are 'secured'

Liu said her neighbors are a little bit afraid of contracting the virus, so some of them have stockpiled goods at home.

But she said she hasn't personally been affected, and she is not the only one who remains confident.

"There are abundant supplies of meat, eggs, vegetables and milk at our supermarket," Li Buyun, manager of Dennis Super Market, told CGTN.

Li also mentioned the measures his market implemented in the face of the COVID-19 resurgence.

"We have our own storage, which is convenient for replenishing stocks. During the outbreak, we've also increased certain amounts of goods in reserve in case of emergencies," Li said.

Li said tighter measures have affected customer flow, but most consumers do not stockpile goods and deprive others.
