I can't remember the title, I think it was one of those old Chinese film series King/God of Gambling...something along those lines. This huge wedding was being shot to shit after the King/God of Gambling won a game against this, I think it was some bitch ganglord who didn't take too well to losing so she crashed the K/GoG's wedding. Another part of that movie later was his revenge and rescue of his fiancee. Gang members were armed with nothing but pistols, looked like M9s but the guy had placed big guns like an M60 and an RPG along these long corridors he retreated when his position gets overrun.
Its probably been almost 20 years since I last saw this movie with a lot of the details being very vague.
"Hey I'm the first one to say its a great country but its a straaaaange culture. This is a place where gun store owners are given a list of stolen credit cards but not a list of CRIMINALS and MANIACS. And now they're thinking of banning toy guns...AND THEY'RE GONNA KEEP THE F**KING REAL ONES!"
