This movie, aka Chin Gei Bin and The Twins Effect, sucked. That was not meant to be a vampire movie pun. The Vampire Effect had lame special effects, mediocre acting, a shitty plot, and a bad ending.
Feel free to consider this a benefit, but it has a cameo by Jackie Chan playing a character named Jackie. But even he used wires in this movie.
It is about European vampires trying to take over the kingdom of the Chinese vampires. They want the secret to being a super, daywalking vampire. Lame. Don't bother.
