Wu Style was developed after the Chen and Yang style, therefore it’s a quite new style.
It the fourth style in terms of family seniority. You may not be able to find a Wu style grand master outside Asia.

This style is different from the Wu style of Tai Chi ch'uan (??) founded by Wu Yu-hsiang.

Wy Style Characteristics

The Wu style's distinctive hand form, pushing hands and weapons trainings emphasise parallel footwork and horse stance training with the feet relatively closer together than the modern Yang or Chen styles.

Wu style contains more small circle hand techniques than the Chen and Yang style.

Wu style's initial focus on grappling, throws (shuai chiao), tumbling, jumping, footsweeps, pressure point leverage and joint locks and breaks, which are trained in addition to more conventional Tai Chi sparring and fencing at advanced levels.

Wu Style Stands and Body Weight

The leg that supports 100% of the body weight is actually the yang leg, as this leg is "full". The yin leg is that which has no weight on it, it is "empty".

It is also common in Wu style to maintain a straight line of the spine from the top of the head to the heel of the rear foot when it is at an angle to the ground; an inclined plane alignment intended to extend the practitioner's reach.
