I started taking wing chun classes afew months ago to strengthen my striking and blocking. I love the class so far and have been studing its history and the applicatonis the entire time to get a full comprehesive grasp on the art. Sadly one thing still has me confused and thats Chi Sau. To me it kinda looks like the equivilant of Uchi Komi in the sense it appears to be a drill that you can do for a viraity of techniques. But I don't get how doing it agments your trappping ablity. Any clarificatoin would be much apericated. I dobut we will be doing Chi Sau for a while considering the instructor just started teaching in NC and all of his studetns are novice's.
