Compared with Waijia Boxing, Neijia Boxing is another practice of Yin and Yang Theory, and the biggest difference is the different understanding and application of the body. The linear relationship between yin and yang points out the difference between internal and external boxing systems. The internal movement relationship between two points is external boxing, just like the line in electromagnetism that opposites attract and don't run between them, which is what we often say. Like archery and axe chopping, it relies on consistency, mostly using contractile muscles in the human body. Between two points, the movement relationship between the external support and the external pull is the internal fist, just like the repulsion of the same sex in electromagnetism, and the movement beyond two points, just like the relationship between the nail and the hammer, relies on the strength of another point, and mostly uses the muscles in the human body to expand. This is why psychological boxing theory has three sections and four strokes. The tip is like a nail, the middle is like a hammer, and the root is like a hammer handle. The muscles in the four tips control the weight and trajectory of the human body, the tendons control the connection and continuity of the human body, and the bones control the vertical pull of the human body and the force and acceleration of the human body. Therefore, China's family boxing system is unique to China Kung Fu in the world Kung Fu forest.

Tai Ji Chuan's theoretical system is a supplement to the nine essentials of psychological boxing, and Xingyiquan is another name of psychological boxing.

His laws and regulations are the treasures of China Wushu culture and play a leading role, and many Wushu schools have benefited a lot from its influence.
