What do you mean by linking back to Beijing?

The link back to Beijing is a short message back to Beijing. Through the link in the short message, you can reconfirm whether you have been to high-risk areas. Wait patiently for the result after submission. Judging from the relevant public information, Beijing's epidemic prevention policy is very strict, but it is also humane enough, and it is relatively humane on the premise of ensuring epidemic prevention safety. As long as it meets the policy requirements, strictly abides by the relevant epidemic prevention regulations, truthfully fills in personal information, and is willing to bear the corresponding risks and consequences on the premise of ensuring no epidemic risk, the community can still successfully enter Beijing.
