Chen Changxing (陳長興 Chén Chángxīng, Ch'en Chang-hsing, 1771–1853), 14th generation Chen Village martial artist, synthesized Chen Wangting's open fist training corpus into two routines that came to be known as "Old Frame" (老架; lao jia). Those two routines are named individually as the First Form (Yilu; 一路) and the Second Form (Erlu; 二路, more commonly known as the Cannon Fist 炮捶). Chen Changxing, contrary to Chen family tradition, also took the first recorded non-family member as a disciple, Yang Luchan (1799–1871), who went on to popularize the art throughout China, but as his own family tradition known as Yang-style tai ji quan. The Chen family system was only taught within the Chen village region until 1928.
