Ask some police to chase ghosts and other movies, modern. Like ghost police, ghost eye police.

You can look at the famous work of Wong Kar-wai and Liu Zhenwei: Ghost, which is very funny and has many stars, but this one is about catching vampires.

There is also a very good one, starring Nicholas Tse and Feng Delun, called 2002 or Supernatural (this is a Hong Kong film name, which is unknown in mainland China, but Baidu should be able to find it). It's about two policemen catching ghosts, and the stunts are not bad. The two heroines are both beautiful, one is Li Caihua, and the other is a girl who often pats the skin of Olay, which is also worth seeing.
