When doing fajin, only go to 80% extension.
The kua goes up to the inside towards the elbow.

First half of the circle, push into the front foot, but the foot does not move.
Compass: one needle does not move at all, the 2nd needle is pinned to the paper but to the table. When moving the compass, the 2nd needle will move around the first needle dragging the paper. The 2nd needle moves on a track (specifically around the first needle).
Those are the 3 kinds of not moving:
- 1st needle - absolutely not moving
- 2nd needle - restrictively not moving (moving on a track)
- 2nd needle and the paper - structurely not moving (between them they didn't move)
