Your arguments begin to convince me...
1) As you say, this film is a co-production, and I know that co-productions use different technicians from the two countries... (the international version of "Wheels on Meals" credited spanish Francisco Riba as cinematographer of that film...). This may explain that HK sources credited "your" cinematographer and China version credited "my" cinematographer.
2) Also is very odd that "my" cinematographer only did 2 films in all his life...
3) Wong worked with Ann Hui in other film...
4) My ONLY doubt is the award. Why they did not put their real name in the nominees list? As you say, we need an chinese editor. Also is very odd that Mr. Deedlee did not post something to crush my theory...
ANNEX 1) BTW, as Mr. Dleedlee, I am also curious about your "Border Crossings"... I want its index post, too (please).
ANNEX 2) In the Chinchanchung's version of Film Book Archive does not appear "Romance of Book..." nor "Princess Fragrance". In the entry that you say 7825 appears the film "Gigolo and Whore II". Do you have another version of the Film Book Archive?
WHERE IS IT?
ANNEX 3) Please, don't remove these photos, this week-end I'll try to add all your valuable information.
ANNEX 4) If I can check that 7825 entry, and nobody objects in
30 days, I will merge the two cinematographers.
