Authorities in China’s southern city of Shenzhen shut the world’s largest electronics market of Huaqiangbei and suspended service at 24 subway stations on Monday in a bid to curb an outbreak of COVID-19. 

Three key buildings in the sprawling area, comprised of thousands of stalls selling microchips, telephone parts, and other components to manufacturers, will stay closed until Sept 2. Local community officials confirmed Monday’s closure, while three people working there said building managers had told them to work from home.
