The most important schools of Chinese kungfu are Shaolin kungfu and Wudang kungfu. Wudang kungfu is famous in China for its internal kungfu with many forms including tai chi chuan, qi gong, bagua, xingyi as well as sword and staff.
—Tai chi chuan (traditional Chinese: 太極拳; simplified Chinese: 太极拳; pinyin: tàijíquán) is an internal Chinese martial art often practiced for health reasons. Tai chi is typically practiced for a variety of reasons: its hard and soft martial techniques, demonstration competitions, health and longevity. Consequently, a multitude of training forms exist, both traditional and modern, which correspond to those aims. Some of tai chi chuan's training forms are well known to Westerners as the slow motion routines that groups of people practice together every morning in parks around the world, particularly in China.
Today, tai chi has spread worldwide. Most modern styles of tai chi trace their development to at least one of the five traditional schools: Chen, Yang, Wu/Hao, Wu and Sun. The origins and creation of tai chi are a subject of much argument and speculation. However, the oldest documented tradition is that of the Chen family from the 1820s.
