Tai Ji Chuan takes boxing frame as the body, internal strength as the foundation, and pushing hands for use. As the saying goes, "If you don't practice boxing, you will get nothing." Tai Ji Chuan is like a rootless tree with no internal work, passive water. The boxing frame became an empty shelf. What is Tai Ji Chuan's internal strength? The so-called internal strength is the internal kung fu. Its essence is the combination of spirit and spirit. It is the essence of China Wushu and Tai Ji Chuan. Tai Ji Chuan's profoundness is mainly reflected in the cultivation of internal strength. Among them, practicing internal qi is the key to practicing internal strength of Taiji. Mr. Feng Zhiqiang, a famous contemporary Tai Ji Chuan economist, said: "To practice internal strength, the first thing is to practice internal qi. Qi is the body of strength, and strength is the use of gas. " In a sense, the internal qi reflects the level of Taiji Kung Fu. Full of internal qi, can protect the body, the body is elastic, such as a ball full of gas, not afraid of being beaten; If the internal gas is abundant, the internal strength is strong and unstoppable; Full of internal qi, dredging meridians, protecting the whole body, eliminating diseases and strengthening the body; With abundant internal qi, when the mind is calm and the body is relaxed, you can circulate all over the body, draw air with your intention, and transport your body with your qi, thus achieving the goal of reaching strength with your intention and being extremely weak all over, thus making the enemy invisible, attacking the enemy unprepared, winning the initiative everywhere. Nowadays, many people practice Tai Ji Chuan, but they often only pay attention to the external movements, but not to the internal strength of Taiji. They pay attention to external sports and are keen on competitions and performances. In order to please the audience, Tai Ji Chuan was danced and gymnastic. The stage is full of dragons and tigers, and the applause from the audience is thunderous. But in the opinion of experts, they can only shake their heads and sigh. Why? Tai Chi is gone. Tai Chi internal skill is gone. Tai Chi preaches lightness, calmness, relaxation, lingering, both internal and external training, combining rigidity and softness, and the whole family is gone. This is no longer Tai Ji Chuan, but Tai Chi exercises with only appearance but no connotation. The internal strength of practicing Tai Chi can not be separated from Dantian. Relax calmly, stay in the abdomen, cultivate the spirit of the abdomen, and constantly strengthen and enrich it. Next week, under the guidance of ideas, it will spread all over the body, open at most four points, and then return to the abdomen. This flow of internal qi is carried out under the guidance of thought and combined with the opening and closing of boxing routines. The so-called "emotional monarch to flesh and blood minister", the appearance action is completely passive, is the result of emotional movement. If you can lead the spirit with your mind and convey your body with your spirit in the process of plate rack, then your boxing rack will have substantial content, that is, you are practicing Tai Chi internal skills. Of course, standing piles and meditation are also good ways to practice internal qi. When the mind is in a state of rest and the body is in a state of relaxation, the Qi of Dantian follows the direction of meridians, opening up the second pulse of Ren Du and realizing Sunday's exercise. This can not only strengthen the body, but also develop Tai Ji Chuan's unique martial arts. Tai Ji Chuan's offensive and defensive characteristics are flexible, landing just right. In addition to posture, technique and footwork, the most fundamental way to effectively resolve the attacking power of the other side is to rely on internal strength. Tai Chi masters can fight when the opponent's body is basically motionless, and rely on deep Tai Chi internal strength to defeat the enemy. Similarly, Tai Ji Chuan's attack also depends on internal strength. When he works hard, it means he is full of energy, which helps boxing. He is strong. Tai Ji Chuan's internal work practice, in addition to abdominal qi, but also pay attention to the practice of waist and buttocks. The key to Tai Ji Chuan's internal strength lies in his waist and buttocks. Tai Chi is alive, but not alive. Look at the waist and buttocks. If the waist and hips are not alive or loose, the movement will be dull. Those with advanced internal skills in Tai Chi are extremely flexible in waist-hip conversion, with extremely small circles and inconspicuous shapes. If there is something, it is hidden, so that the other party does not know its depth. Otherwise, it is easy to see the flaw for the other party, which is not done by the master. The waist and buttocks are not loose, the internal qi is difficult to enter the ground, the body pile is unstable, and it is difficult to defeat the strong hand. Waist and buttocks are the secret of Tai Ji Chuan. Without this mystery, it is difficult to practice Tai Chi Kung Fu. Therefore, we must pay attention to the cultivation of internal strength when practicing Tai Ji Chuan. Pay attention to the cultivation, expansion and operation of internal forces. This is the basis of practicing Tai Chi. Taiji's martial arts rely on internal strength, and health preservation also depends on internal strength. Only by practicing both inside and outside can we practice Tai Ji Chuan well. "Cultivate its roots, branches and leaves and nourish its sources and veins." Therefore, grasping the abdomen and practicing internal strength is the foundation of practicing Tai Ji Chuan.
