Aon is correct there are two wu styles, wu and wu (-hao). The 'wu' for each style is pronounced differently and the 'hao' is sometimes added to the one style to make it even more clear which wu style you mean.

Which Wu style do you mean? There are two styles with the name Wu, although written differently in Chinese - Wu (武氏) sometimes referred to as Wu-Hao, and Wu (吳氏).

If you want to understand Wu style, do a search for Stephen Hwa.

He has excellent understanding of Wu Taiji.
