At this point I we understand that several members of the forum think that you have to fight to learn how to use wing chun.
Could we take it to the next level please? What has fighting taught you exactly? For example It would be instructive if someone said I was taught to do bong sau this way but I have found when fighting it is better used that way.

This is a wing chun forum after all and once upon a time discussions actually talked about how to use wing chun.
