I called this local college (RPI) to ask about teaching Wing Chun there. The guy said, "We need your certificate to teach." The thing is, maybe they gave out certificates when I attended the school in the Ip Ching lineage, but the guy I learn from now does not do that. (For the record, he is in the lesser-known Leung Sheung lineage.) The only thing that happened was he said to me, "You know, you can teach people too." That was it! Then the RPI guy proceeded to ask me what rank I held. I said, "We don't have ranks." He said, "Aw, that will be a problem too." Where the hell do you go to get a certificate for something where no certificate is offered???
