What is the purpose of observing joint defense in kindergarten?

The purpose is to ensure the normal development of children's bones.

The observation of protecting joints in kindergarten is to find children with abnormal skeletal development in time and correct their wrong sitting posture in time, and the ultimate goal is to ensure the normal development of children's bones.

In infancy, children's bones are fragile. If the child has a hunchback at this time, it can be corrected within one to two months.
