To cope with the challenging situation of epidemic prevention and control, 31 provinces, municipalities and autonomous regions released rules for trans-provincial travel. People from different risk-level areas have to abide by the following requirements or possess the following materials when traveling to the indicated cities:
To Beijing
From low-risk areas: a green health code, register personal information on the JingXinXiangZhu (京心相助) WeChat mini program, make contact with their community or company in advance. People from low-risk areas under closed management in Beijing should have their health conditions monitored locally for 14 days.
From medium-risk areas: a negative nucleic acid test report conducted within 72 hours before boarding; a 14-day home observation or isolated observation when the conditions for home observation can't be met.
From high-risk areas: a negative nucleic acid test report conducted within 72 hours before boarding; a 14-day isolated observation.
Anyone in close contact with a confirmed or asymptomatic case should have a strict "14+7+7" health management service – a 14-day isolated medical observation at designated sites such as hotel rooms, followed by a 7-day home monitoring of health conditions, with an ensuing 7-day general monitoring of health conditions.
