If my memory serves me right is not the name Wing Chun named after the training hall that Lei Man Mou practised at the Northern Shaolin Temple befor it was destroyed ? or have I lost the plot ? and getting a bit mixd up.
Yes mufty, memory is a tricky little devil isn't it? Well, let's see. The famous Wing Chun Din was more probably at the southern temple. [More probable would be that this famous hall might have been located at the Honam Temple and it's ideas spread southward to the southern 5 Elders, but that's just speculation on my part. Although I'd prefer to hear what an expert would say on the subject. Actually there was a very well written article by Sal Canzioneri based on the subject at hand.]
It is were, according to a version of Wing Chun lore, the Wing Chun system was originally devised by the Southern Siu Lam elders. Elders such as Jee Sheem, Miu Hin, and Ng Mui might have developed and perfected the different animal techniques and deviced, what I would like to term as, a proto synthesis of what was later to become Wing Chun Kuen. After the burning of the southern temple the system was propagated along the (in)famous Hung Suen or Red Boats. Lei Man Mou was a member of such a troupe. When the rebellion that he pertained to failed and the opera disbanded, the system was spread thoroughout the different regions of southern China. One of it's most famous recipients being the city of Guang Jau or more commonly known as Canton.
I hope I have cleared the waters up a bit.
It is amazing for me to understand that "unexplainable" no longer has to mean "nonexistent". pp172
