Hsing I Ch'üan

Allegedly created by General Yue Fei during the Ming dynasty, Xing Yi (also, Hsing I) is one of the most powerful and linear looking of the internal martial arts. Its primary strategy is to aggressively occupy the opponent's territory and is often likened to rolling over your opponent with a huge iron ball.

As an internal art, however, Xing Yi's power is derived from relaxation, focusing the intent (Yi) and the development of internal energy (Qi). It is based on the Daoist philosophy of the 'Wu Xing' or five elements and uses this framework to devise its defensive and offensive strategies.

Xingyiquan features aggressive shocking attacks and direct footwork. The linear nature of xingyiquan hints at both the military origins and the influence of spear technique alluded to in its mythology. Despite its hard, angular appearance, cultivating "soft" internal strength or qi is essential to achieving power in Xingyiquan.

The goal of the xingyiquan exponent is to reach the opponent quickly and drive powerfully through them in a single burst — the analogy with spear fighting is useful here. This is achieved by coordinating one's body as a single unit and the intense focusing of one's qi.

Efficiency and economy of movement are the qualities of a xingyiquan stylist and its direct fighting philosophy advocates simultaneous attack and defense. There are few kicks except for extremely low foot kicks (which avoids the hazards of balance involved with higher kicks) and some mid-level kicks, and techniques are prized for their deadliness rather than aesthetic value. Xingyiquan favours a high stance called S?nt?shì, literally "three bodies power," referring to how the stance holds the head, torso and feet along the same vertical plane. A common saying of xingyiquan is that "the hands do not leave the heart and the elbows do not leave the ribs." The use of the Santishi as the main stance and training method originated from Li Luoneng's branch of xingyi. Early branches such as Dai family style do not use Santi as the primary stance nor as a training method.

Five Element form

Xingyiquan uses the five classical Chinese elements to metaphorically represent five different states of combat. Also called the "Five Fists" or "Five Phases," the Five Elements are related to Taoist cosmology although the names do not literally correspond to the cosmological terms.

Xingyiquan practitioners use the five elements as an interpretative framework for reacting and responding to attacks. This follows the five element theory, a general combat formula which assumes at least three outcomes of a fight; the constructive, the neutral, and the destructive. Xingyiquan students train to react to and execute specific techniques in such a way that a desirable cycle will form based on the constructive, neutral and destructive interactions of five element theory. Where to aim, where to hit and with what technique—and how those motions should work defensively—is determined by what point of which cycle they see themselves in.

Each of the elements has variant applications that allow it to be used to defend against all of the elements (including itself), so any set sequences are entirely arbitrary, though the destructive cycle is often taught to beginners as it is easier to visualise and consists of easier applications. Some schools will teach the five elements before the twelve animals because they are easier and shorter to learn.
