Tai Chi Sword and Tai Chi are essentially a movement skill influenced by Chinese culture. Its aesthetics is in line with the aesthetics of traditional culture, which is consistent with the aesthetics of calligraphy, classical philosophy, and traditional Chinese medicine theory. The words "spirit, shape, function, rhyme, image, and momentum" mentioned in the question are the first time I have seen them. In the process of learning martial arts, no one has used these words yet. In the competitive martial arts Tai Chi circle, the four terms "form, strength, intention, and energy" are commonly used. If it is a competitive competition or participating in a performance, then the rules are the content of the athletes' study. Specifically, how many angles and how high? How low is what athletes have to do. Of course, ordinary enthusiasts or traditional Tai Chi are not within the management scope of competitive martial arts and can freely express themselves. Regarding these six words, my understanding is:
Shen: spirit, consciousness, thinking, emotion, feeling, Shen in traditional Chinese medicine explains the functions of the human body, the external manifestations of thinking and limbs, and in Tai Chi Sword, it is to show the golden mean, to be powerful but not angry. Harmonious but not weak, there are needles hidden in the fabric. It seems comfortable and easy-going, but it can also become stronger when strong.
Shape: The external body shape of the movements is soft but not stiff, strong but not stiff, and heavy but not heavy. Heavy, light but not floating. The movements must not only conform to the principles of attack and defense, but also comply with the requirements of using the mind to guide the Qi, so as to use the Qi to convey the force, the Qi reaches the intention, and the energy reaches the point.
Usage: Moves. Offensive and defensive applications.
Rhyme: Tai Chi has a unique charm, a balance of hardness and softness, a balance of yin and yang, a continuous connection, and more randomness based on one's own circumstances, focusing on smoothness, comfort and comfort. Just feel comfortable and experience beauty by yourself, entertaining yourself and others.
Image: real and virtual images or bionics, such as wild horses. Mane, white crane spreading its wings, these movements are bionics, and the display of movements has artistic conception or image.
Momentum: momentum, momentum, posture. What moves is momentum, such as posture, which looks static on the surface. , in fact, it is the "posture" of form, which contains potential energy. After it moves, it becomes kinetic energy.
