陰陽相濟

 陰陽相濟

身手輕靈與貫串是推手「牽動四兩撥千斤」所必須具備的要素。身手輕靈毫無拙力與企圖心，才能黏貼跟隨對手身體的重心，輕靈是身體放鬆境界的表現，有輕靈而後才能貫串，貫串是合唯一，是身體整體能量的整合。輕靈與貫串如同陰與陽的對應關係，在彼此互動中產生剛與柔、動與靜、虛與實之間的現象，擅用陰陽變化的對應關係，讓對手難以捉摸陰陽變化的脈絡。尤其兩手、兩腿與身體巧妙的陰陽變化，彼此相互合作，相互協調，更能將「以柔克剛」的技藝發揮到極致。

這也是訓練腿力、扎根，及鬆腰落胯，氣沉丹田的訓練法。

Lightness and connection are essential elements for achieving the principle of "using four ounces to deflect a thousand pounds" in Push Hands. Lightness of the body is free from stiffness and intention, allowing one to adhere to and follow the center of gravity of the opponent's body. This lightness is a manifestation of physical relaxation, and only when one achieves lightness can one attain connection. Connection represents a unity where the overall energy of the body is integrated.

Lightness and connection correspond to the relationship between yin and yang, creating phenomena of hardness and softness, movement and stillness, emptiness and reality in their interactions. By skillfully utilizing the corresponding relationship of yin and yang, one can make it difficult for opponents to grasp the subtle changes of these forces. Particularly, the clever interplay of yin and yang in the hands, legs, and body enhances mutual cooperation and coordination, allowing the technique of "overcoming the hard with the soft" to be brought to its fullest expression.

This also serves as a training method for building leg strength, grounding oneself, relaxing the waist and hips, and sinking the qi to the dantian.
