Hsing I (Xingyiquan) T'ai (Roc) take down (Jiang Rong Qiao style).

The T'ai is a mythical ancient bird. It has also been called a 'Roc:' (n. Mythical bird of prey having enormous size and strength). The motion associated with this animal is sometimes likened to an ostrich (using wings to distract or grab and beak to bite). This animal of the 12 Animals of Hebei style Hsing-I Ch'uan is the one that has the largest variation in both the Animal name and description, with different versions that range from a winged dinosaur to a camel. The T'ai is sometimes represented as a descendant of an Archaeopteryx. Other groups sometimes describe the T'ai as having large wings like a Terasaur. A number of schools refer to the T'ai as an ancient large bird. It is possible, for example, to envision something like the now extinct flightless Moa (from New Zealand) and related large birds.
