Please revise your story, Mak chin Ching is the disciple of Chow Long.
Chow Lung is the older brother in the Chow family , the founder of the Hung Toi Choy Mei
( Chow Gar Ku Fung) around 1914-1915. During that time Mak Chin Ching and Chow Biu were 16 year old, they both were born at the same year, they both were learn Ku Kung Fung from Chow Lung. in China before 1919 in China. Both relationship were very close like the brother.
After the second wold war, Chow Biu had always came to my father’s place in practicing Ku Fung with my father at 150 Ye Kowk street Kowloon Hong Kong around the decade of the 1950.
So Mak Chin Ching is not the disciple of Chow Biu.
