Videos of clashes between police and people being forced out of their homes in Shanghai has gone viral on the internet as the city enters a third week of Covid-19 lockdown.
Some residential compounds are being turned into quarantine centres.
Millions are confined to their homes as Shanghai battles a fresh outbreak of the virus. Anyone who tests positive is placed in quarantine.
But with more than 20,000 new cases a day, authorities are struggling to find enough space.
The city in recent weeks has converted exhibition halls and schools into quarantine centres, and set up makeshift hospitals.
But the low numbers of serious cases in Shanghai have led some to ask whether a lockdown is necessary, correspondents say.
In recent weeks many residents have taken to social media to complain about the restrictions and the lack of food supplies.
People have to order in food and water and wait for government drop-offs of vegetables, meat and eggs, and analysts say many are running low on supplies.
The lockdown extension has overwhelmed delivery services, grocery shop websites and even the distribution of government supplies.

But this zero-Covid policy has come under strain in recent weeks with the spread of the Omicron variant.
