Does Lanzhou need to be isolated from Beijing?

No need for isolation.

Optimize the policy of returning to Beijing to ensure the normal exchange of personnel. People who have lived in counties (cities, districts and banners) where 1 case of COVID-19 infection occurred in the local area within 14 days will be strictly restricted from entering and returning to Beijing, and those who have lived in this area will be strictly restricted from entering and returning to Beijing within 7 days. People from other counties in the prefecture-level city where one or more local COVID-19-infected people are located, as well as people from counties where land border ports are located, are no longer restricted from entering and leaving Beijing. At the same time, in accordance with the principle of "prevention and control first, overall consideration, steady and orderly progress", direct flights to Beijing international commercial passenger flights will be resumed in batches and in an orderly manner.

Resolutely control imported risks and build a barrier for prevention and control in the capital. According to the current domestic epidemic situation, we will continue to implement remote screening measures. Passengers who plan to return to Beijing can return to Beijing normally with the negative certificate of nucleic acid test within 48 hours and the green code of "Beijing Health Treasure". Under the premise of normal temperature measurement and personal protection, nucleic acid test will be carried out within 72 hours after arrival in Beijing. For commuters, continue to implement the negative certificate of nucleic acid test within 72 hours after returning to Beijing and the "Beijing Health Bao" green code policy. After completing the "7-day centralized isolation +3-day home health monitoring" in the local area, the entry personnel from other domestic ports can enter and leave Beijing normally within 48 hours with the negative certificate of nucleic acid test and the green code of "Beijing Health Treasure".
