Chan Koon-Pak (1847-1920) was the second son of Chan Heung, founder of Choy Li Fut Kung Fu. After his elderly brother Chan On-Pak passed away, he carried on the banner of the system. In the beginning, Chan Koon Pak wanted to become a merchant in the city of Kong Moon (modern day Jiang Men). His friends and family members persuaded him to teach the system of Choy Li Fut founded by his father. Under this constant pressure and encouragement, he finally took the position to be the chief instructor of the Hung Sing School of Kong Moon. He produced many outstanding students in Kong Moon before he moved to Canton (today known as Guangzhou). He appointed his top student Chan Cheong-Mo to take over the Hung Sing School in Kong Moon. Grandmaster Doc-Fai Wong’s teacher Wong Gong was one of the permanent students of Chan Cheong-Mo.
