Very interesting. I can see a resemblance between the man in the pic and the The brothers, look at the nose. They have the same grandmasters story, same story about using Japanese style uniforms. There is no mention of Ie being related to Hiang Sr, they are listed as both being direct students of Su Kong. But why would Sin and Hiang never mention their father as one of their teachers? It doesn't make any sense. I did hear Sin The tell a story about an ancestor of his, great great grandfather or something, who was a martial arts expert. So he did acknowledge in an off-hand way that martial arts have been in his family for multiple generations, it just seems strange that it's never mentioned as part of the proud lineage. Did their father not actually teach them, because he wanted them to learn from someone else, like the story of Wong Fei Hung being sent to his father's friend to learn martial arts, because Wong Kei Ying felt he couldn't be strict enough with his own son? It just doesn't make sense for any of these people to lie about or hide anything based on what we know. Maybe someone involved was a wanted criminal, and their true identity is being protected (Ie Chang Ming did supposedly kill some soldiers). However, it seems like the The family was quite well-off, Sin even mentioned that the ancestor in his story was a wealthy man who had servants. Organized crime? Weird, weird, weird.
