Apart from the fact that this is virtually the only published source of information on Bak Mei kung fu, it is also an excellent book! To be truthful it is not really a teach yourself book, but then you cannot really teach yourself a martial art like Bak Mei from a book. It is however facinating to read a genuine Masters thoughts, and most importantly this is a rare opportunity to see previously unpublished photos of the late Great Master Cheung Lai Chun. Probably the best ...I ever spent!!
