The Chen-style tai chi (Chinese: 陳氏太极拳; pinyin: Chén shì tàijíquán) is a Northern Chinese martial art and the original form of tai chi. Chen-style is characterized by silk reeling, alternating fast and slow motions, and bursts of power (fa jin).
Traditionally, tai chi is practiced as a martial art but has expanded into other domains of practice such as health or performances. Some argue that Chen-style tai chi has preserved and emphasized the martial efficacy to a greater extent.
