Baguazhang or Pakwachang is one of the three main Chinese martial arts of the Wudang school, the other two being T'ai chi and Xing Yi Quan. It is more broadly grouped as an internal practice (or neijia quan). Bāguà zhǎng literally means "eight trigram palm," referring to the trigrams of the I Ching (Yijing), one of the canons of Taoism.
