Help! Looking Ringo Lam's "City On Fire"

I have been looking for this film for a little while now, and can't find it anywhere. There is a DVD version of the film with a blue version of Chow Yun-fat's face on it. But that version is an English dub of the film. There is supposedly a DVD version that is in the original language with English subtitles, but I am unable to find that version anywhere. If anybody knows where to find the sub version of the film, please let me know!
