...Hsia Hou Lan...It is not our "unknown actress 2
I agree with you on this one now as I blindly went with my IMDB entry for 'Forbidden Tales..' trusting my assumption that I filled the entire cast there a few years back however upon 2nd glance today, I realize that I didn't originally update/specify the role of 'Mrs. Sha' there & curiously within a week since my reply here, it has disappeared telling me that whoever originally updated that actress I suspect retracted it after reading this thread! For DB data that's open & therefore up for grabs in the vast Wiki-community, my mistake was relying on the data in that entry that I had originally authored & assumed accurate (but not for that actor). There's enough evidence here to support 'unknown actress (2)' not being Hsia Hou-lan. Will follow-up.
Tam Ying: Possible, but I need a proof.
Of course you do; but for this one I'm 100% certain. I'm going on my non-leftist Chinese film history here but I know for a fact that industry leaders (notably dtr Li Han Hsiang in the 60-70s) were responsible for placing many Shanghai film expats in character/extra roles within the Hong Kong industry post 1949. Hsin Hwa, Great Wall, MP&GI & Shaw studios were all built on this brain-trust & tradition. Personalities such as Yen Chun, Hung Po, Liu En-jia, Ching Miao, Chien Szu-yin, Wang Yin, Li-li Hua, Li Ying, Pai Kuang, Ouyang Sha-fei, Li Yun Chung, Erh Feng, Wang Lai, Chen Yen Yen, Ho Li-jen, Butterfly Wu & Tan Ying were all part of that 1st generation of Mandarin-era reclamation thespians in HK who got new leases on their careers. (if you've managed to get outside the curtain, it's safe to say for them it beats the alternative for artists & intellectuals being retooled for performing for the people's agricultural or military rally films as part of some re-education program during the cultural revolution).
Can't give you links by others cuz little or none exist (if they do, I see you guys already found it), so my own visual proof is forthcoming.
