SiuLum Studio's Southern Style Kung Fu offers training in the martial arts of the Fujian province of Southeastern China. Our curriculum is based on the Tiger Crane system which combines the two most famous Fujian styles.
There is a southern Fujian style called the "Tiger Crane Combination" which is a mixture of Yong Chun White Crane and Grand Ancestor (Tai Chor in Hokkien).

It doesn't to my knowledge have any link with Hung Ga in general and in particular WFH Hung Ga and it's Tiger Crane form.
