Yiquan, also known as dacheng quan, is a martial art system which was founded by the Chinese xingyiquan master, Wang Xiangzhai (王薌齋).
Yiquan is essentially formless, containing no fixed sets of fighting movements or techniques. Instead, focus is put on developing one's natural movement and fighting abilities through a system of training methods and concepts, working to improve the perception of one's body, its movement, and of force. Yiquan is also set apart from other eastern martial arts in that traditional concepts like qi, meridians, dantian etc., are omitted, the reason being that understanding one's true nature happens in the present, and that preconceptions block this process.
The actual training in yiquan can generally be divided into:
- Zhan zhuang (站樁) Standing pole postures where emphasis is put on natural condition, working to improve listening to the body and on developing hunyuan li, "Natural living force" or "all things that make the whole".
- Shi li (試力) Testing force moving exercises, trying to bring the sensations of hunyuan li developed through Zhan zhuang into movements.
- Moca bu (摩擦步) Friction stepping Shi li for the legs.
- Fa li Emission of force a practice later dropped by Wang.
- Shi Sheng Producing sound with voice a high level occurrence, only relative to those with formidable understanding already in place.
- JiJi Fa Real combat not sparring.
