Taiji Quan, famed for its graceful, meditative movements and focus on internal energy, was introduced to the An family by Qu Ke Zhang, a close friend of An Ji Hai and a Taoist monk from the Jing Yi An Temple in Tian Jin. Qu studied an ancient style of Taiji, passed down by Taoists from the Wudang Mountains, and excelled in Taiji sword forms. His education was enriched by interactions with numerous martial arts masters, including Cheng You Long, the son of Bagua Zhang master Cheng Ting Hua.
