Kung Fu: Caine vs 2 Martial Artists

This clip from the classic 1970s TV series "Kung Fu" was taken from the episode called "The Tong" from Series 2. Starring David Carradine as Caine and Richard Loo as Chen. Unfortunately I am not sure of the names of the 2 martial artists in this clip but this is the link for the full cast list... http://www.imdb.com/title/tt0623201/fullcredits?ref_=tt_cl_sm#casthttp://www.imdb.com/title/tt0623201/fullcredits?ref_=tt_cl_sm#cast
