Thirteen strokes of Taiji is a traditional boxing method in China, which belongs to one of the schools in Tai Ji Chuan. Tai Ji Chuan's principle is: "People (Tai Chi) use rigidity (two instruments), hit eight directions (eight diagrams) with their hands, and jump five positions (five elements) with their feet to complete a series of actions, which must be represented by five lines of gossip in fighting. The eight methods correspond to the innate eight diagrams, each of which is basic, and the five-step method corresponds to the five elements, each of which is appropriate and reasonable. "
To sum up, it is "Tai Chi, Eight Diagrams and Five Elements". It can be seen that the thirteen potentials of Taiji are not some fixed movements and postures, but some rules of attack and defense, the nature of strength and the method of exerting strength, and the method of drumming.
Based on the theory of boxing, the originator of Tai Ji Chuan observed the relationship between Yin and Yang, the relationship between Yin and Yang, the coexistence of Yin and Yang, and the endless and overly popular movement.
