All good, as I've said before (and will say again) all of these are just legends anyways. Every WC origin/ancestor myth should be taken with enough grains of salt for 100+ bowls of soup. The interesting thing about Li Wen/Man Mao is that I've never really found much that points to him being a martial artist, though some people have claimed he knew one of the 7 or so versions of white crane that would have been available around that time. For me, I find it plausible that there was a separate cell under the same rebellion of which someone of some (but not the highest) status knew wing chun (Hung Gun Biu). As Li Wen Mao was a pretty big figurehead, I think it probably would have been more well known if he was a wing chun expert/creator. That even the white crane thing isn't 100% certain makes me doubt the connection, as most of what my line has about Hung Gun Biu talks about his fighting ability and what he contributed to our system, as well as his role as a Hung Gwan of that particular revolutionary cell. Also, this is the same time that Wong Wa Bo was learning/had learnt Wing Chun, isn't it strange we'd be certain that some random actor knew wing chun but not someone who was a leader of a famous uprising?
