Form and meaning are not only fist and fist kung fu, but also have rich and profound connotations. Mr. Guo, the predecessor of Xingyiquan, said: "The way of Xingyiquan is to practice to change people's spiritual temperament and restore people's true colors." There is a saying in "Single Crystal" that "quietness is the noumenon, movement is the function, the chapter is invisible, inaction is achieved, quietness is Fukashi, and the feeling moves with it" is also the application of practicing magical powers, and there is a cloud: "Sit-in kung fu is breathing prancing, in harmony with the spirit, popular in one breath, endless in circulation and stagnant. This is a kind of kung fu, seeking to move in silence. This seems to be different from seeking quietness in martial arts movements. In fact, the truth inside is the same. " Quiet kungfu is the best and most fundamental kungfu to get rid of illness, strengthen the body and prolong life. It is a real "Tao" and is not comparable to ordinary "techniques".
