There are thirteen basic moves in taijiquan. These are combined in the 88 forms
of Yang style taijiquan. The eight tactics are pang (ward off), lui
(swing with transverse motion), jai (press against wrist). on
(press
down obliquely), choi (pull down), lit (swing up), jau (elbow),
kau (lean). In addition there is movement in five directions: forward,
backward, left, right and center.
After the opening form comes Grasp the Swallow's Tail, which is made up of the moves
ward off, swing transversely, press, and press down
obliquely. Below is a pair of photographs,
with the solo form on the left and the pushing hands application on the right.
