The Vietnams Wing chun under nguyen te cong has chi sau with tan and fook sau, there not ym or yks.
You didnt point out anything, the reson i said there are pollitics in wing chun is because of egos, look in the mirror.
what wing chun system do you do edmond do you enjoy it? do you have the long pole form or is it the shorter form? i ask because im interested about wing chun not to say your story has faults but to ask about ur systems. we are always learning if you are open to it.
I remember reading a quote about a famous yip man student who when asked if it was possable if there was wing chun in a communist country like vietnam that it was impossable.
Glad there are people with a open mind and not just people like yourself with a closed mind
