Hey everyone!

I have been doing Xingyi for a little and have just learnt the Pi Chuan METAL ELEMENT and i must say i like it very much.

I would like to know more about how the elements interact and also about when to use them. I would also like to know what you people think about the following points...

METAL: Is aimed as a strike behind the enemy
WATER: Creates a gap (great against Wing Chun)
WOOD: Has the most powerful straight punch in the world!
FIRE: Is a technique used in "celestial step"
EARTH: Is the most difficult element to master

Any thoughts?

Many Thanks

S
