Return of the Master Killer

hey,

i have this dvd and on the backcover, there are scenepictures of the film but i don't think that's the scenes of the movie. I don't know if somebody has this dvd but on the back there are 3 pictureS and if you watch the movie ,you don't see any of that. and that's strange! but i did see a trailer on the master killer dvd that probably looks like the movie of that 3 picture. maybe it's difficult to understand. is there a switch?? i liked that trailer that i saw and it says that it is the trailer of Return of the Master Killer but i don't think so! it hard to find out bec there are 3 different english traslation of a every chinese movie. does anyone knows about that trailer? what is the real title of this trailer?
