Why should your thumb be pointed when you tie your feet?

Foot-binding, also known as foot-binding, foot-binding and foot-binding, is to wrap a girl's feet tightly with long strips of cloth, which makes them slim and causes deformity of foot bones. In ancient times, foot binding usually began at the age of five, because at that time the bones were tender and shapeless. The toes were pointed with the thumb of the foot, and the other four points were wrapped with hard objects. The molded feet are in the shape of zongzi (so many people think that the Dragon Boat Festival is an auspicious day for foot binding). It is also necessary to wrap the broken ceramic pieces in the foot cloth, and then wrap them tightly until the blood oozes, once in the morning and once in the evening, until the woman gets married. Once wrapped, it cannot be removed, because it is also a kind of protection.
