Master Yang Chengfu Yang Chengfu (1883-1936) modified and opened to the Chinese public the formerly held secret Yang Family Style Taijiquan (tai chi). He developed a system of taijiquan that differed from that of this father, uncles and grandfather. He reduced or eliminated many of the difficult high kicks, leaps and stomps, replacing them with wider more comfortable stances with smoother flowing, light, agile, rooted movements; thereby making taijiquan more accessible to the general public.Nevertheless his style was strict and demanding—some say he even created a more effective martial art. He called his style Yang Big [or Large] Frame (Yang Da Jia).
