As one making the transition from Shaolin to Hsing Yi and Yi Quan, I'd like to get some thoughts and coments on the following subjects.

1 The use of Yi in striking I have heard it said to focus your yi thru your opponent as if you are striking behind them, though others have said to focus the yi into your opponents core.

2 The use of angry eye versus soft eye. I find the use of angry eye causes alot of tension. which decreases power.

3 The use of noise; Yi Quan uses aahhh or haaa. Tai Chi has hung and ha and Hsing Yi uses the sound of thunder. personally, I find it distracting to try to make noises during practice.

Your thoughts and comments would be greatly appreciated.
