Dear Master Chen,
If I listened correctly youbut rotate to change angles. I have a question about the . In the first half if you lead with the elbow it seems the angle in the elbow gets sharper. Is that a move or does that happen through rotation? As far as know a isn’t considered a movement. Also what happens when you keep “pushing” the elbow in the line of the shoulder and hand to create power? It look likes the elbow is dropping away from the line which should make the structure weak. I can’t seem to unite these directions although I think I understand them separately.
