Two styles of tai-chi chuan were developed by people named Wu though they were unrelated and form distinctly different branches of the evolutionary tree. The older of these is often referred to as Hao style or Wu/Hao style. Both of these styles are comparatively rare in the UK.
The older and least common of the Wu styles originated with Wu Yu-hsiang (1813-1880) who learned from both Yang Lu-Chan and Chen Qing-Ping. Although the overall sequence appears to owe more to Yang style, the influence of the small, subtle movements of the "Zhao Gao" Chen style tai-chi is also clearly evident.
Wu/Hao style utilises the compact nimble movements, agile steps and short range techniques of small frame tai-chi. This graceful style has an upright stance and is practiced with simplicity, clarity and softness.
Wu Chien-Chuan (1870-1942) developed the more prevalent of the two Wu styles. He learned from his father Wu Chuan Yu (1834–1902) who had in turn learned from Yang Ban Hou, the second son of Yang Lu-Chan.
The style is characterised by its medium frame. The movements are gentle, unhurried and are performed at an even tempo. They typically retain the inclined postures reminiscent of "old Yang" and emphasise parallel footwork and horse stance.
