All supermarkets and small convenience stores in residential communities in Changchun, Jilin province, resumed remote business operations on Friday to meet people's daily needs, officials said.

"Residents can only purchase via online platforms, telephone or WeChat, and commodities will be sent to their doors to avoid any touching," Zhang Li, deputy director of the provincial Health Commission, said at a news conference on Friday.

Changchun had suspended all such business on Sunday, and only online service was available via several designated platforms.

The city carried out its 11th round of mass testing on Friday, during which residents were required to wear N95 face masks dispatched by community workers.
