At an Ikea store in Shanghai, cameras captured chaotic scenes of customers trying to escape as security tried to quarantine them.
Health officials intended to lock down the store in the city's business district because customers had allegedly been in contact with a person who tested positive for Covid.
Guards are seen closing the door as the crowd pushes inside and makes an escape route.
Shanghai faced a very strict two-month lockdown this year.
Since then, in accordance with the state strategy zero Covid policies, in a city of 20 million people, entire areas where new cases and their close contacts were recorded were ordered to be immediately closed.
Many are locked in unusual places in fast food restaurants, gyms and offices.

The sudden closure of the Ikea store was due to close contact with a six-year-old boy who was confirmed to have Covid after returning from Lhasa, Tibet, Dandan Zhao, deputy director of the Shanghai Health Commission, said on Sunday.
He did not say when the close contact was in the store.
Those found at an Ikea store in nearby areas must be quarantined for two days and monitored by health officials for five days, Zhao said.
By Sunday, nearly 400 close contacts of the six-year-old boy - who had no symptoms of infection - had been caught, while 80.000 were required to take PCR tests, the Shanghai Daily reports.
Ikea customer service said on Sunday that the store was closed due to an increase in the number of cases.
The flagship store in Xuhui District, opened in 1998, was the first Swedish furniture store in China. Today there are 35 of them across the country.
China persists in its zero-tolerance policy in preventing the spread of the corona virus, despite the fact that it has a significant impact on the economy and there are more and more people who oppose it in public.
Panic scenes from Ikea videos from last week show people in another part of Shanghai running out of the building amid rumors of abnormal corona test results.
During the lockdown in Shanghai this year there were many reports of food shortages and the poor living conditions people faced in quarantine centers.
Annoyed residents were filmed brawling with covid wardens and screaming from their windows to protest the restrictions.
