Both Chan Heung and Jeung Hung Sing's schools were deeply connected to the Hung Mun. All the way up to the Xinhai revolution that overthrew the Qing in 1911. Choy Lee Fut people were heavily instrumental to the Hung Mun. Now, it's my personal opinion that Chan Heung's first teacher was one of the Five founders of Hung Mun. Jeung Hung Sing was also a student of one of the hung mun five founders. The five founders were shaolin monks. What many people don't realize when "Shaolin" was the focus.....not all shaolin temple's were named "SHAOLIN". Knowing this, the temple the five founders were members of may not have been titled "SHAOLIN" but under a different name, while still being shaolin.
