How do you do reversals in VF4?

How do you do reversals??? I am new to VF4, and dont know how to reverse attacks from my opponents. My fav characters are Lau and Lei Fei.

 

Chars that you use can't do reversals.

 

Then how do I evade or dodge moves?

 

all you do is tap up (or down depending on where you want to go) and hit P+K+G , this is the standard side step move (every character has a sidestep then hit P+K+G move)

 

dude, do you even have the game???? go on training mode / trial.
