Sorry the Youtube Quality was not as well as I hoped (worst was opening therefore no credits). Some names copied from HKFA a still puzzling me...
1) There is a Zhang De-Liang billed as "Widow" (??) but there was another widow played by Tin Mung - i could only notice one widow anyhow...
There are unknown: 2) Zhang Zheng-Xin 3) Zhai Bei 4) Xiao Yang 5) Huang Yong-Yi 6) Fei Qing-Xiang (Who was "Ma Ke"?) 7) Lin Ying-Zhao Chang Pai
Maybe some of them are early stage names for unbilled actors like Chai No...? then I failed to spot Law Hon; Wang Dan, Ling Yun (who is billed twice by HKFA)

Still most of the cast (at least 14 actors) is used in the "Poisonous Rose" too- for example:

is http://hkmdb.com/db/movies/image_detail ... ay_set=eng

Not much help:

I only GUESS Ling Yun could be a mistake.

could be a second Seung Fung image.

Yes Michael I thought the same!
