Please help with this. In particular I'm referring to Yip Man & his closed door students. I always thought that it referred to his closest students that were taught more as disciples than students, learning a little more than everyone else "behind closed doors" as it were. But someone told me today that it referred to the students Yip Man kept teaching after he retired from full time teaching (due to illness) and after he "closed his doors" on his teaching.
Which is right? Are both right?
I know that all families of Wing Chun tend to believe themselves the sole inheritor of the complete Wing Chun system (two worst than most-but that's beside the point & I don't want a mud slinging match) so I'm not really interested in "My Sifu's Sifu learned from x, & he says this so it must be right", just the facts if such can be established.
Thanks!
