The same movie:

and

http://hkmdb.com/db/movies/view.mhtml?i ... ay_set=eng

WOMEN BLUE is the title of the Korean version, very likely added to the hkmdb with data from the Korean Movie database.

Same cast (except the Korean actresses who are not credited or credited with different names in the Hong Kong version).
I guess Lau Chi-Wai (2) in the cast of WOMEN BLUE is Lau Chi-Wing.

Look also at the posters to see same motives.

If no one objects I merge the two movies.
