Heavy police presences have prevented a possible resurgence of protests against the government's tough zero-Covid policy in several Chinese cities.
In the capital Beijing and in metropolises such as Shanghai, Guangzhou and Hangzhou, security forces have been on the streets since Monday.
In many cases, passers-by were stopped and had to show their mobile phones, which were checked for suspicious content or programs such as tunnel services (VPN) to circumvent Chinese censorship.
The police officers are also said to have deleted photos of protests from devices.
In Beijing, the Liangma River promenade near the diplomatic district, where hundreds had demonstrated on Sunday evening, was particularly secured.
In Shanghai, barriers had been set up on Wulumuqi Road to prevent larger crowds like at the weekend.
After calls for new protests on social media, a massive police presence was also seen on People's Square in the eastern Chinese port metropolis, as eyewitnesses described.
Protests in several cities
Thousands of people took to the streets in several cities in the People's Republic over the weekend to protest against the rigorous measures of the zero-Covid policy, such as repeated lockdowns, forced quarantines, mass tests and constant monitoring of corona apps.
In Beijing, "lift the lockdown" and "we don't want PCR tests, we want freedom" were shouted.
These were the largest protests in China since the pro-democracy movement, which the military brutally crushed in 1989.
According to the National Health Commission, China recorded 38,645 new corona infections after 40,347 infections the previous day.
3822 of the cases are symptomatic.
36,525 are asymptomatic infections that are counted separately in China.
The country reports no further deaths related to the virus within a day.
The official number of corona deaths in China remains at 5233.
