A pointer in 'Pushing-Hand'

explained by Master Chow as he demonstrates on 2^nd April 2012.

1. that as the opponent exerts strength, you relax. And as he relaxed, you will exert instead, keeping the Ying & Yang flowing non stop.
2. when the opponent relax, you will have to instigate him to exert strength. You will have to 'tempt' him by exerting (or attempt to exert) strength yourself.
3. Only when the opponent exerts strength then you can make use of his strength (or force) and turn it back against him.
4. And the moment to do so is at the split-second when he is at the tail end of his exertion and just before he can relax. This is the best moment to strike back for it is his weakest moment, when he starts to lose his balance. And he will require double the amount of time, to (i)stop and balance and then (ii)strike back. To be able to sense this moment is the most difficult to master.
