There were chaotic scenes at an Ikea store in Shanghai on Saturday, with shoppers trying to escape as authorities tried to quarantine them.
Health officials were attempting to lock the store in Xuhui district down as a customer had been in close contact with a positive Covid case.
Videos show the guards closing the doors at one point, but a crowd forced them open and made their escape.
Shanghai endured a severe two-month lockdown earlier this year.
Since then, in line with the country's strict "zero-Covid" strategy, the city of 20 million people has ordered flash lockdowns of areas where positive cases or their close contacts have been detected.
