How to Return His Force?

One question that keeps coming to mind is how to return an opponent's force back to him.

When there are two points of contacts, that is easy. For example, if his force is coming towards your right, you can relax your kua and let him push your right, while using your kua to redirect his force towards your left and returning it to him. But that can only be done if both left and right are in contact with him.

So when you only have a single point of contact? After all, even if you absorb his force from the start, if you want to return it to him after that, won't you end up resisting his force?

Actually, the key lies in first relaxing the kua, as usual, then absorbing his force (same). Next is to first redirect his force away from you in a circular manner, and continuing the circle, return his force back to him. When redirecting his force, you must first peng, then stick to him, before using your kua to turn yourself towards the direction that you want his force to go in.
