Chengdu has become the latest Chinese city to be locked down as Beijing continues to pursue its controversial "zero-Covid" policy.
Around 21 million people have been ordered to stay indoors, with just one person per household allowed out for essential shopping.
On Thursday, the city recorded 157 new infections, including 51 asymptomatic.
China's Covid policies require cities to enter strict lockdowns - even if just a handful of cases are reported.
