Unfortunately there is a lot of lousy information in the self-defense community. A great deal of traditional martial artists use pure lies to maintain their self-anointed position as “master”.
One of the worst is Master Wong. A supposed Wing Chun expert, he somehow manages to show how his stuff is so superior to other proven fighting methods like BJJ or MMA without ever actually showing himself testing his methodology against a truly resisting opponent with opposing will, malevolent intent, and freedom of action.
Let me be clear – his stuff is pure garbage at every level. But don’t believe me, watch this excellent video that puts his ideas to a legitimate test and the results show how spectacularly it fails. Watch if for yourself, and the next time you see one of Wong’s promotional BS vids on YouTube or social media, you will know how truly crappy it is.
