The martial art of &”;practicing one breath inside&”; has been lost for a long time, and Tai Ji Chuan&;s function of strengthening the body is more just a wish. Chinese Wushu emphasizes &”;training muscles and bones outside and breathing inside&”;, which makes sense. Exercising muscles and bones outside is nothing more than strength and skill, which is easy to understand and I won&;t go into details. It is the essence to practice a breath inside, but it is helpless to inherit the date, and the rivers and lakes are in chaos, especially as follows. The essence of internal training is to mobilize one&;s body and internal organs, and use breathing to make the muscles and joints of the back, waist, buttocks and neck near the spinal (central) nerve move in the direction of infrequent exercise, disturbing blood stasis, dispersing blood stasis, drawing wages from the root, liberating nerve and blood vessels, fully guarding the immune system with blood flow, preventing and treating diseases before they occur, and maintaining health. It should be noted that the source of many diseases may be strain. Work and siltation, siltation and accumulation, accumulation and pressure, pressure and resistance, resistance and loss, and strain. Overwork leads to siltation, siltation leads to loss, and overwork leads to illness. The main points of internal breathing are: breathe in and hold your breath, aiming at inflating the lungs to form a compressed sphere, which can spread the muscles and joints related to the spine from the inside out, such as the intervertebral joints of the spine, the joints between the ribs and the spine, the hip joint and the shoulder joint, etc., in coordination with the body movement and the movement of the abdominal viscera. Take a breath inside. There are many moves. You can practice standing, sitting, lying down, walking and driving … See January 28th, 2019, November 14th, 2018, and May 26th, my home page. However, I can&;t take it away without thanking you. Take a breath inside, don&;t stick to all kinds of routines, and don&;t care about those mysterious ones. However, the technique has revealed its essence and covered its moves. Including Tai Ji Chuan, and the routine, failed to grasp the root cause of strain, and failed to grasp the key point of removing silt, with vague thoughts, different actions, and poor results. When you preach martial arts, you can experience prosperity and experience decline. The clever and capable Wulin predecessors summed up the incisive &”;breathing inside&”; by experience in practice, and Wushu entered a prosperous period. Due to the lack of modern scientific knowledge, such as biology, anatomy, chemistry, mechanics, etc., it is impossible for the predecessors to understand deeply in theory, and it is impossible to have a clear interpretation of words and images. Everything is taught from heart to heart and passed down from master to apprentice. The longer the succession, the more vague, the more diluted and even lost. Later generations practice martial arts only according to legends and imagination. Thousands of people have different opinions and are at a loss. They can never find the true meaning of &”;taking a breath inside&”;. People with active minds are full of words. Successful people are puzzled, covered in circles by specious things, very distressed, and even possessed. Taking a breath inside, such a superb skill was born in the experience of the ancestors, but it was forgotten in the follow-up of the younger generation, confused and confused, and the martial arts went into the night. Taoism is divided into hundreds, and &”;practicing in one breath&”; conceals its true nature, which leads to Tai Ji Chuan and other martial arts rivers and lakes with various routines and sects. Anyone, any organization, as long as he emphasizes a certain special, routine, sect, can judge that he still doesn&;t understand how to practice inside, and he doesn&;t really.Kung fu. If Tai Ji Chuan wants to realize the function of keeping fit, he must take a breath. If you want to take a breath, and it is limited to Tai Ji Chuan, that is, you are not on the road. Therefore, at the beginning of this article, it is said that Tai Ji Chuan&;s function of strengthening the body is more just a wish, or just a language skill. Accurately understand the core meaning of &”;taking a breath inside&”;, say less about Tai Ji Chuan, this routine and that school, and let&;s see the light of day and carry forward Chinese Wushu. Come on.
