I don't know if it's a Hong Kong or a Taiwan production. I don't know the year neither. I tried to write down the chinese characters of the title.

Mr. Seven and Dumb Girl

I would like to add here that missing film, but I need the year...
Are you sure that the year does not appear in the final credits (with the copyright) with the rest of the crew (cinematographer, music, editor, etc.)

According to to this it's a Taiwan production, I think:

And the photo of the woman above looks to me like Sylvia Chang

Literal translation:
出品/出版: 台灣. 合眾電影(香港)有限公司,
Product/Publication: Taiwan. Gathers numerous movies (Hong Kong) Ltd. Co.

maybe a co-production?

Sylvia Chang does not appear in the credits. And I think that woman resembles more to one of my aunts than Sylvia...

These are all the credits available on the vcd. We could credit an estimate year - say 1983, as in the Crazy Youth entry - and later try to find the correct info. The only thing we have to discover is if it's a Taiwan movie, a Hong Kong movie or maybe a co-production. I can just confirm that Sylvia Chang isn't in the cast.

OK. Added.
This is your first "genuine" new movie suggestion.
