The Yang family first became involved in the study of t'ai chi ch'uan (taijiquan) in the early 19th century. The
founder of the Yang-style was Yang Lu-ch'an (楊露禪), aka Yang Fu-k'ui (楊福魁,
1799–1872), who studied under Ch'en Chang-hsing starting in 1820. Yang became
a teacher in his own right, and his subsequent expression of t'ai chi ch'uan became known as the Yang-style, and
directly led to the development of other three major styles of t'ai chi ch'uan (see below). Yang Lu-ch'an (and
some would say the art of t'ai chi ch'uan, in general) came to prominence as a result of his being hired by the
Chinese Imperial family to teach t'ai chi ch'uan to the
elite Palace Battalion of the Imperial Guardsin 1850,
a position he held until his death.[2]
Yang Lu-ch'an passed on his art to:
his second son, the oldest son to live to maturity,Yang Pan-hou (楊班侯, 1837–1890), who was also
retained as a martial arts instructor by the Chinese Imperial family. Yang Pan-hou became the formal teacher
of Wu Ch'uan-yu (Wu Quanyou), a ManchuBannercavalry officer of the Palace Battalion, even though
Yang Lu-ch'an was Wu Ch'uan-yu's first t'ai chi ch'uan teacher. Wu Ch'uan-yu became Yang Pan-hou's first
disciple. Wu Ch'uan-yu's son,Wu Chien-ch'üan (Wu Jianquan), also a
Banner officer, became known as the co-founder (along with his father) of the Wu-style.
Yang Chengfu removed the vigorous Fa-jing (發勁 release of power) from the Hand (solo) Form, as well as the
energetic jumping, stamping, and other abrupt movements in order to emphasise the Da jia (大架large frame
style), but retained them in the Weapons (sword, saber, staff and spear) forms.[3]The
Hand Form has slow, steady, expansive and soft movements suitable for general practitioners. Thus, Yang Chengfu
is largely responsible for standardizing and popularizing the Yang-style t'ai chi ch'uan widely practised
today.
