Four Metro and over 200 bus lines in Shanghai will restart operations from Sunday to connect downtown districts, airports, railway stations and hospitals, the city's vice mayor said on Thursday.

The Metro lines 3, 6, 10 and 16 will initially resume services along with 271 bus lines to meet the basic travel demands of citizens, Zhang Wei said.

A negative PCR report made within 48 hours is required to take the buses, Metro and other transportation. Also needed will be venue code, green health code and temperature checks, as well as facial masks.
