Is the swing amplitude of sandbags good or small?

This involves the boxing theory of traditional Wushu. To put it simply, (for simplicity, "the kicking method of sandbags will shake" is set to 1 and "not moving" is 2). 1 can kick people back, the strength stays in the superficial layer of epidermis and muscles, and the strength of 2 will penetrate into the body, causing deep shocks, such as visceral injury and concussion. The reason is that the way of exerting force is different, and it can only be understood but not expressed; There is no attack intensity and more scientific, just different application scenarios and tactical requirements. 1 Suitable for dealing with weaker opponents or tactical interception, that is, in the face of stronger opponents, kick them away and distance themselves. Suitable for meeting gangsters to protect themselves, causing tons of damage to gangsters with one leg in the past, and evacuate immediately. Remember that real combat is to defeat the enemy with one move!
