http://hkmdb.com/db/movies/image_detail ... ay_set=eng = Jacky Yeung Tak-ngai?

http://hkmdb.com/db/movies/image_detail ... ay_set=eng = Yuen Wo-ping? (only problem is mole on wrong side of jaw. Cd be due to reverse angle of projection)

http://hkmdb.com/db/movies/image_detail ... ay_set=eng = wong yiu (2)?

All the above named actors are asst action directors of the movie except Yuen Wo-ping.

Sorry to say that but in my opinion you are wrong with all IDs.
