"Who knows about me" - http://hkmdb.com/db/movies/view.mhtml?id=15013
and
"Final mission final" - http://hkmdb.com/db/movies/view.mhtml?id=12943
is the same movie.

The original title is "Who knows about me" and the year is 1983
"Final mission final" is the title of IFD release. As far as I know, it wasn't included in any cut-and-paste movie, but released as it is with the differnt title.

So, merge needed.
So far added 6 actors to "Who knows about me" page. I'll upload credits soon.

If nobody stops me in 15 days I will merge them.
