I read recently in a Kung Fu magazine that Emin Bozetepe called out William Cheung on a challenge, counted to three then took him successfully to the floor in front of a live audience.
Did this really happen? Anyone with a reliable source on this?
Also, anyone with reliable sources on the question of whether or not William Cheung was exclusively and secretly taught the only "unmodified" system of Wing Chun by Yip Man and told to keep it a secret unil Yip Man died?
