I suppose this entry was added to the DB using the data on this page: https://cmpctw.pixnet.net/blog/post/1342136
The cast, writer and director are from The Funny Vampire (http://hkmdb.com/db/movies/view.mhtml?id=12895), while the Chinese title is very similar to the 1986 CMPC production also called Reunion (http://hkmdb.com/db/movies/view.mhtml?id=11815)
The description on the pixnet page matches 1986's Reunion and mentions that film's stars, writer and director. So, it's just a weird mistake by whoever put the pixnet page together. I think 18431 should be deleted.

Other than the pixnet entry having 1975 as the year of the film, I agree. I will remove 18431 in a few days.

(and FYI - if at any time something is removed, but is later deemed to have been incorrectly removed, I can usually bring things back into the DB from past points in time from backups.)
