Master Black Belt
Well, There was this one Sifu who supposely didn't complete the entire system.
Another thing the guy did was challenge other schools. They would challenge and Win. He defeated top sifus and his lower ranking students beat upper level students from other schools.
I think I'm familiar with this story. I identify with this fellow, I've had to leave federations because of, well, just moral reasons, arrogance, and corruption.
I think your hubbie could get his top students to great fighting stature, Then challenge other Wing Chun schools as well as other Martial art schools to sparring matches. After he and his students start to win these bouts. Then his name will ring out among the people. He will respected for his title. An those who dare say well he aint really a sifu will always have to cowtow and say he great fighter. "I can't beat him." "But I still say he aint no sifu even though I cant beat him fighting.".
Unfortunately, for me, his top student is I. We've moved alot due to work issues, and teaching at recreation centers is sketchy. When we had the building open for the school he had 20 students in 6 months. (then the entire street flooded three times in two months!) His two top male students both moved to the Phillipines, and got married. (the first one when I first started learning, the second one whom we both taught for 2-3 years! ack!)
Being at a new rec. center with no advertising, he's got about three students right now. We figure the best way to make some noise is to get in a cage match, video it, and slap it on the web.
