我们常讲，太极身法运阴阳。打拳中的阴阳指得是什么呢？从内功的角度来说，阴阳首先是意念的虚实。在实感内功中，意念不是抽象的，而是实实在在的感觉。运阴阳就是训练桩身的感觉和手臂的感觉。感觉什么呢？感觉用力的程度。要做到用力无过，用力无过就是放松。所以运阴阳桩法的根本是训练放松。

We often say that tai chi moves Yin and Yang. What is Yin-yang in Tai Chi exersice? From the perspective of the internal skills, Yin-yang is first of all the mind-leading status. In Renhe Tai Chi Internal Skill, the mind-leading is neither abstract nor imaginary, but real feelings called as Being Sentience. The movement of Yin-yang is to train the feeling of the body and the arm. What does it feel like? Feel the degree of force. To achieve no excessive force, no excessive force is the relaxing. Therefore, the fundamental of Yin-Yang Stance is to train relaxing.

打拳没有绝对的放松，因为你时刻都在用力，桩身要支撑，要保持平衡，手臂也在做各种各样的动作，所以我们说用力无过就是放松。怎么才能做到用力无过呢？靠感觉。运阴阳桩法就是教你用感觉控制用力。比如感觉要隨着桩身重心走；比如感觉肘腕的沉坠等等，练起来一点都不神秘，立杆见影。

There is no absolute relaxation in Tai Chi, because you are exerting force all the time, the pile body should be supported, the balance should be maintained, and the arms are also doing all kinds of movements, so we say that exerting force is relaxation. How can we make no effort? By feeling. The yin-yang pile method is to teach you to control force with feeling. For example, your mind and feeling should always follow the center of gravity when the body moves, and to feel the weight of the elbow and wrist from time to time. It's not mysterious to practice.

运阴阳桩法就是给你解决方松的问题。它通过松肩肘，抬手臂的心法，训练手臂的放松，达到用力无过；通过不倒翁，马步桩心法，训练桩身的放松，达到虚实分明；通过野马分鬃拳式进行综合性的训炼，实现身法的虚实变换，实现用力的放松无过。这样为套路的内练打基础，为今后的推手训练打基础。

The Yun Yin Yang stance is to solve the problem of the relaxing. It trains the relaxation of the arm by loosening the shoulder and elbow; it train the relaxation of the pile body through the Tumbler mind-leading, the Horse step pile, to achieve a clear distinction between virtual and real; Through the comprehensive training of the Wild horse's mane, the virtual and real transformation of body is realized, and the relaxation of force is realized. This will lay the foundation for the internal skill in the routine and for the future push-hand training.
