It appears that Xiao Kao Shan (Siu Ko San, Hsiao Kao Shan) is an alternate name for Ma Chin Ku. Some films in which Ma Chin Ku is very prominent, but was NOT listed in the cast, and Xiao Kao Shan WAS listed in the cast, are: Female Chivalry, The Dragon Kid, Master of the Flying Guillotine, 13 Styles Strike, Incredible Kung Fu Mission. Accordingly, the DB entry for Xiao Kao Shan has been deleted, and all data has been merged into Ma Chin Ku, with appropriate aliases. <br><br>
