The motoins of 1st set of shadowboxing are simple and moderate. It focus on soft and pliant stength. So the boxer should exercise it slowly, pliantly and steadily. He must pay more attention on the exercise of the strength in order to taste difference and unification between movement and unmovement, soft and strong. Because of flexibility, the 1st set of shadowboxing is not only for strong person to exercise, but also for weak and ill person to self-strengthen.

The 2nd set of shadowboxing, also named Paochui, is different. It emphasizes on the strongness and speed of motions. So there are lots of jumping, scurrying and shifting motions in this set. Though it looks no differences with other Kongfu, this set has features of its own. That is it also pay attention to the eddying, eddying of waist, eddying of wrist, eddying of ankle, and eddying of the whole body. And the exerciser could taste the interlink between outward and inward motion. Because of speed and strength, this set is only suit for the youth and person with good body.

Boxer could know the relationship between soft and strong through exercising shadowing. He also could know how to deal with the attack through exercising Tuishou. Tuishou is a special practice created for fighting. It emphasizes the fighter should retaliate following the attack from others. He fast, you should faster, and he slowly, you should more slowly. That is the spirit of Tuishou and Shadowboxing.

There are some kinds of shadowboxing, such as YANG's, WU's and SHUN's Shadowboxing. But all of them are based on CHEN's Shadowboxing.
