In the past, the so-called boy kung fu refers to some basic skills practiced since childhood. Because I have been practicing since I was a child, my kung fu is very solid, and it is easy to practice various martial arts when I grow up. Children's Kung Fu in Shaolin Temple includes basic movements such as leg press, Swallow Balance, and one-legged squat. Of course, there are also some hard and soft kungfu, called childlike innocence kungfu, which means it is more suitable to practice from an early age. Such as golden bell jar, iron cloth shirt, etc. However, there is no clear scope of boys' kung fu, which kung fu includes and which does not, and there is no clear definition. Generally speaking, some kung fu that is difficult for adults to practice and easy to get hurt can be called childlike innocence. Iron cloth shirt is relatively easy to practice, much easier than golden bell jar, so it can only be regarded as a boy's skill, or it can be said that it is not. Most kung fu, as long as it will not affect the child's physical development, is generally more appropriate to practice from an early age. Hard work is harmful to the body and is not conducive to the development of children. Therefore, the general practice of external skills is not a boy's work, only internal skills can be a boy's work.
