The third one could be in the cast list of one or more of the movies he appear.

ID of "29". His name is Yue Man-Wa:

One reason for the ID was SHANTUNG MAN IN HONG KONG (updated cast list).

Did also ID of the actor Tu Chia-Cheng (I add soon more images and search for more movies).

I think more IDs are possible with SHANTUNG MAN - see my unknown actors I added to the cast.

"Richard Lo/Liu Kong" in the cast list looks for me like a possible alias for Chiu Liu-Kong (still no identification!).

ID of Unknown SB-Actor 31 as Woo Ping (1):

http://hkmdb.com/db/people/view.mhtml?i ... ay_set=eng

Name and actor in The Night the Spirit Returns, Story of Sword and Sabre, Aftermath of a Fire, They All Fall in Love, Three Encounters and Her Tender Love (fixed on that movie wrong image ID of Woo Ping).
Added a few new images to AFTERMATH 1 and 2 (updated cast) and to Woo Ping more potrait images.
