for tai ji
1 grasping the sparrow's tail
2 cloud hand
3 covering body fist or bie shen chui
4 kao, most of the moves/postures may contain or end with kao
bie shen shui can be bie shen kao etc
--
I pick them because
1. restraining arm, wrist and elbow
2. deflecting to the side (peng la and lu) to defend against arm and elbow
3 covering our front and then introducing fist, wrist, elbow or shoulder
4 kao is a big thing in Tai ji, lots of people ignore this, ouch
