This is a short summery on research I have done through both readings and speaking to various Sifus on the historical changes to Yip Man's wing chun curriculum, from teaching in Foshan to Hong Kong. Age 24 (1917 - Yip Man returns to Foshan): -Mook Jong had several different short forms -Bat Jam Do form non-existent, drills used instead -Chi Sao not practiced till after Cham Kiu (approx 3 years) -Siu Nim Tao practiced for at least 2 years before Cham Kiu learned -No footwork till Cham Kiu (just turning stance) Age 45 (1938 - Yip Man teaches neighbours wing chun for self defence vs Japanese): -curriculum restructured to increase combat skills quickly -Footwork taught almost right away -kicks simplified -wooden dummy forms combined, result is one single form of 72? moves -only kick on wooden dummy now is front kick -Cham Kiu taught after 1 year -Chi Sao introduced after a few months -No Bat Jam Do or Staff taught Age 56 (1949 - Yip Man flees to Hong Kong, teaches full time): (At this point, he needed a curriculum that would keep students interested and quickly start wining at beimo fights to attract more students. The curriculum also needed to last longer to retain students over a longer period of time): -Mook Jong form increased from 72? Moves to 108 then 116 then back to 108 -footwork and chi sao still introduced as soon as possible -more kicks reintroduced to Mook Jong -Bat Jam Do form created? Or at least learnt from Yeun Kay Shan and the taught -Staff form taught / created As you can see from above, Yip Man's curriculum changed depending on the circumstance he found himself in.
