Improvement of children's floating fingers and inner crotch walking

The back of the pelvis makes it difficult to open the hip joint. Rather than the hip joint itself, it is necessary to pay attention to the linkage between the pelvis and the hip joint. In addition, there are many children who spend time sitting on the floor from childhood, and if there are many flat sitting and side sitting, it will cause the alignment of the hip joint and pelvis to break, so I want parents to observe carefully.
