Do children learn social security and break off relations across regions?

Not exactly. Social security broke off, enterprises no longer pay social security for employees, and social security stopped. Only after the insurance needs to be renewed can the social security card continue to be used. Cross-regional social security refers to the fact that the household registration and student status are not together, and children participate in the basic medical insurance for urban and rural residents and the basic medical insurance for students. There is no restriction on the region, and the social security card can still be used, which is not considered as broken.
