SUISHU - TUI SHOU
In combat contact between your and your opponent's hands happens very often. The training method known as tui shou (pushing hands) prepares you for such a situation. People who saw Tai chi chuan tui shou or Wing chun chi sao can have some idea about tui shou practice in yiquan. As you know, yiquan is mostly about working with a "force" called hunyuan li. Tui shou is really just about this same. From this point of view tui shou is shi li with partner. During tui shou practice you learn to feel opponents force and it's direction, his strong and weak points and his ability of keeping balance. All this in order to develop ability of controlling opponent, changing direction of his force, putting him off balance, putting him into inconvenient position, opening space for attack. Some important points of tui shou practice are:
Dian (point). It means point of contact between you and opponent. In this point you feel opponents force, its direction, if he is stable or not. In this point your force acts on opponents body.
Zhi li (pointing force). There should be some force in the point of contact, directed towards opponents center line.
Jie (section). It means sections of body and limbs. Important is understanding how force is transferred.
Xie mian (oblique surface). Receiving opponents force in adequate way, enables dividing it into smaller forces.
Ganga li (force of leverage) and Luoxuan de yunyong (using spiral movement) help to use bigger force with less effort.
Gong fang he yi (merging attack and defense into one). Attack suddenly becomes into defense, defense becomes attack. One movement can be attack and defence.
Shou zhong, yong zhong (guard center, use center). Control opponent's center and don't let him attack your center.
Quan shen zhi fa (method of using whole body).
Tui shou is not just "pushing hands". You should use your whole body in co-ordinated manner. Steps should aid body and hands.
Although we learn some movements in tui shou, it's only starting point in pushing hands practice. In san tui shou (free tui shou) you should be able to act in myriad's of situations and not just use some sets of techniques.
