Its believed that Damo created shaolin kung fu.many researchers disagree. Like the famous researcher Tang Hao. I read the book of Sal Canzonieri (The Hidden History of the Chinese Internal Martial Arts) and i noticed that the name of Yue Juen (the creator of the shaolin 5 animal style together with Bai Yu Feng and Li Sou) the name given by the Tang dynasty to Damo (Yuen Jue) is but reversed.
If we refer with Damo to Jue Yuen, then the story is true. Jue Yuen collected old forms and lost shaolin knowledge and created the shaolin kung fu curriculum with base the 18 luohan techniques. the mythological Damo also created shaolin kung fu from the 18 luohans.
I noticed also in Sals book that Bai Yu Feng was called Jin na luo. He is the protector deity of shaolin martial arts, and that Li Sou the Dahong style introduced to the temple. The Dahong style included Hong quan, Pao quan and Taizu chang quan. Maybe he introduced the Hong quan style into the temple.
According to Meyr Shahars book Shaolin monastery, the henan shaolin temple was not destroyed during the Qing dynasty, but during the end of the Yuan dynasty by bandits. The Yuan mongols also prohibited the training of martial arts and so it is logical that Jue Yuan lived during the Ming dynasty and his work was to save the lost shaolin knowledge from the shaolin ruins.
All three of them with Jue Yuans 18 basic luohan techniques, created many luohan quan forms and many other styles.they can be called as the shaolin kung fu creators.
