Shijiazhuang, Hebei province, downgraded all its high- and medium-risk areas for coronavirus to low as of Monday.

"The city had reported no new locally transmitted COVID-19 cases since Jan 19," said Jiang Wenhong, deputy mayor, at a news conference on Sunday.

"Gaocheng district — the worst-hit area in the city — finished mass nucleic acid tests on Sunday, and all results have come back negative."

He added that public cultural venues, including libraries, museums, galleries and stadiums would resume operations.

As required by local government, the venues must keep the number of visitors on site below half their designed capacity.

Mi Zhiqi, director of the city's bureau of transportation, said that inter-provincial and intercity bus services will resume.

After showing an ID card and registration information, passengers will be allowed to enter and exit bus stations, provided they have a green health code and normal temperature.
