Yes, interesting. Have been following this connection of fact-finding and link to the Red Boat Opera. It is likely that someone or multiple WingChun practitioners from this period in time also traveled/fled to the Mt. Emei, Sichuan Province and influenced some of the Buddhist monks in this Southern MA skill-set during this era of political unrest. There is that other historically documented Southern TCMA sect that has remained silent in this heated discussion and seems to reserve this right. I have communicated with one of their practitioners on the issue and will leave it at that.
