Hskwarrior,
Hi, I was google browsing n’ happened to come across this information from the Bullshido website about the Green Grass Monk and Choy Lee Fut. I thought you’d find this interesting as I see you're into the history and all.
“Ok, there’s been a lot of myth and mistake here regarding CLF. CLF was founded in 1836 by Chan Heung in King Mui Village, Toisan County, Guandong province. Chan Heung intitially learned Nan Sil Lum Hung Men Kuen from his uncle Chan Yuen Woo from the age of 8. Chan learned rapidly, and in his early teens his uncle sent him to train with his Sihing, Li Yao San. Li Yao San was the founder of the Li Gar system, one of the 5 families of southern Shaolin. Over the course of 10 years Chan learned the entire Li Gar system. Li then sent him out to find Choy Fook, AKA the green grass monk. After eventually persuading Choy to take him on as a student, Chan learned northern shaolin and Lohan Qigong from him.
In 1836 Chan returned to King Mui and opened up his school, the Hung Sing school (from this point referred to as Chan Hung Sing lineage). One of Chan Heung’s top students, Jeong Yim was sent to Futsan to run a Choy Li Fut school there. Jeong’s system evolved, placing great emphasis on long arm power. This line is now referred to as Jeong Hung Sing. One of Jeong’s descendents, Tam Sam, established a school in Kwongchow, but later moved to Hong Kong. Here he met and befriended the Northern Shaolin Master Ku Yeo Cheung (Wing Lam’s Sigung). This led to an exchange of ideas and students which led to the development of the Bak Sing Lineage (also known as Bak Sing Fut Gar).
It would be innacurrate to say that CLF is reliant on expansive circular techniques. Indeed, as has already been mentioned, a stabbing, linear leopard fist punch is a hallmark of the style. It does express full extension more than Hung Gar, and the footwork is more agile and dynamic, but the two are clearly related. Close range techniques are emphasised just as much as the long (if not more) and sticky hands is a fundamental part of training.”
