Martial arts practitioners are all masculine. To practice Tai Ji Chuan, we should combine rigidity with softness to achieve the goal of balancing yin and yang. "Taiji Biography and Spectrum" says, "A hundred tempering steels are indestructible, first extremely soft, then extremely firm, and soft on the outside and rigid on the inside. It contains firmness, unintentional firmness, but inner softness. " Tai Ji Chuan must not lose her femininity: the whole body reciprocates, based on spirit and qi, and naturally runs through after a long time. To practice kungfu, first practice the hard into the soft, then practice the soft into the hard, the soft into the hard, and the hard into the moderate, only depending on the balance of Yin and Yang. Soft is yin, just yang. Only by combining rigidity with softness can the theory of Yin and Yang be adapted. Therefore, those who learn to practice Tai Ji Chuan must first destroy their rigidity. Then use flexibility to direct actions. All schools of Tai Ji Chuan law have maintained the style of "combining rigidity with softness, hiding needles in cotton". In fact, there is no such thing as "pure softness but not rigidity". Let's talk about Tai Chi Chuan. Flexibility without rigidity cannot defeat the enemy, and rigidity without softness is also difficult to win. Tai Ji Chuan used in body-building exercises should balance the physiological balance of human body with "combining rigidity with softness" and "combining rigidity with softness".

Fourth, cooperate with each other from top to bottom

"Up and down follow each other" is also a kind of "yin and yang are mutually rooted". The upper part is yang and the lower part is yin. "Up and down" here refers to the coordination of limbs up and down, with hands following the footsteps and heels touching the ground. "On the Biography of Taiji" said: "It is rooted in the feet and legs, mainly in the waist, and the shape is in the fingers. From feet to legs and waist, you have to finish it all the time. " The relationship between feet and hands is like this, but the waist is the center and plays a leading role. The head, trunk and limbs of every movement should move with the waist. Physically, advocating "from top to bottom" is to seek the coordination of Yin and Yang, the harmony of Yin and Yang, and the cooperation of up and down, so as to achieve the realm of "moving is moving, moving is moving". Tai Ji Chuan's walking action is "moving the body with heart qi" to achieve "intention without exertion", which is also done according to the theory of Yin and Yang. Because the heart belongs to the internal yin and the force belongs to the external yang, "the heart is at the same time" and "yin and yang are born together", the mind moves to the next action, which is called "moving without moving, especially not moving" "Constantly" move one after another, and complete a full set of actions from beginning to end according to the law of Yin and Yang.

Five, flowing.

Although clouds are "passers-by" in nature, if there are no dark clouds in the clear sky in Wan Li, the sun will flourish and the yin will decline. If it doesn't rain for a long time, there will be a drought, and the dark clouds will roam, the yin and yang will be reconciled, and then it will rain, which will bode well for a good year. Supplementing yin and yang with clouds is also the way of yin and yang in boxing: running water begins in a mountain stream and flows in a stream, and yang is used to tonify kidney and yin essence. Here and there, one yang and one yin converge into a broad and harmonious river, in which water quietly develops its unique nature and supreme virtue. It nourishes all things and does not compete with all beings for profit. It has remained in a low position all its life without a complaint. If we can live as naturally as water, we can live happily. My mind is as still as water, so deep, I will be quiet and forget myself; Treating others selflessly like water can nourish everything and imitate heaven; If you keep your word, you can keep your word; If you lead a clean and honest life politically, you will certainly be able to govern the political country well; Work, like water, is shaped by things, and it can give full play to its talents; Action, like water, dries up and overflows at any time, which will follow the trend. Every day, water has such a virtue. No wonder the first sentence of the eighth chapter of Tao Te Ching written by Laozi, the founder of Taoism, is "If the water is good". Wang Zongyue's "Tai Ji Chuan Classic" compares the gentle and continuous movements to "flowing water", and recognizes that water is a good species commented by experts of Yin and Yang: hitting Tai Ji Chuan with "flowing water" can gain the aura of flowing water, moisten the heart and sow the seeds of longevity.

Sixth, the cultivation elements.

The fundamental purpose of practicing Tai Ji Chuan is to strengthen the key body. Finally, Chen Xin's reference to Tai Ji Chuan's classification mentioned "cultivating the primitive". Because "the heart is the master of the whole body and the kidney is the source of life". The main means to cultivate its roots is exercise, and the best sports day is Tai Ji Chuan. Because Tai Ji Chuan's theory contains the way of keeping in good health of Yin and Yang. "You can't say anything in a thousand words, but if you are pure in heart and want nothing, you will be better than others in terms of vitality and physical strength." Mencius said, "A master must teach people by rules." What are the rules for practicing Tai Ji Chuan? It is a fist classic, fist score and boxer based on the theory of yin and yang. As the saying goes, "self-learning without a teacher". Boxing for nothing, there is no fixed frame. Why should we follow the rules and not stick to the rules? On boxing "punch 10 thousand times, god shows himself" If you want to get the way of keeping in good health from Tai Ji Chuan's theory, you must honestly follow the theory of Yin and Yang, be familiar with Tai Ji Chuan's classics and keep exercising for a long time. As the poem says, "Everyone has his own Tai Chi, but he doesn't study hard. As long as he can make unremitting efforts for a long time, the wonderful cycle will naturally pass. "
