Page "Yang-style t'ai chi ch'uan" Paragraph 6

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.

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.
