Also, supermarkets and other offline stores of key suppliers are gradually resuming business. As of Friday, 1,011 non-epidemic-hit stores of major supermarkets had opened. The number of employees had increased by 37 percent compared with the previous period.

To further improve the efficiency of distribution, some supermarkets in the economic hub have launched a variety of supply packages involving necessities such as rice, noodles, vegetables, fruits and toiletries, which will be delivered to local communities through third-party logistics companies after residents report their needs to neighborhood communities or place orders on the supermarkets' apps, Liu said.

The city has strengthened health testing for anti-epidemic workers including delivery people, providing convenient testing services.

Shanghai adopts a "2+2" testing mode for logistics workers, requiring them to take two antigen tests every other day, and one antigen test and one nucleic acid test the following day.
