Traditional Yang Style Tai Chi Chuan was originally founded by Yang Luchan. His famous grandson Yang Chengfu developed the style, the movements became slower, bigger and more open.
Characteristics are the steady flow, the harmonized connection between body and mind and a strong internal energy. Yang Chengfu said, Tai Chi Chuan is an art, in which the slow and soft movements contain a strong internal force like a ‘needle concealed in cotton’.
