Is there any requirement for Beijing Changping to go to Hebei Huai and back to Beijing?

Need to do nucleic acid. Passengers who plan to enter and return to Beijing can normally enter and return to Beijing with negative proof of nucleic acid test within 48 hours and green code of "Beijing Health Treasure" on the premise of normal temperature measurement and personal protection, and conduct 1 nucleic acid test within 72 hours after arriving in Beijing 24 hours. Note: Those who have lived in infected counties (cities, districts and banners) in COVID-19 within 7 days 1 case or above are strictly restricted from entering and returning to Beijing. Huailai commuters are commuters and continue to implement the negative nucleic acid test certificate within 72 hours after returning to Beijing and the "Beijing Health Treasure" green code policy.
