But such teachers are rare, and it is usually a big mistake to hit the soles of the feet. The teacher will make the students who make mistakes take off their socks, kneel on the chair, put their feet out of the chair, and then hook their feet hard to make the soles of their feet completely straight.

Teachers usually hit the soles of their feet no more than 30 times. After all, feet are the most important part of dance practice. If they are broken, dance practice will be postponed. If you hit them moderately, you will have a long memory.
