What is the Hong Kong drama in which a male policeman and a female ghost cooperate?

It should be Crossing the Enchantment, a suspense detective drama produced on 20 10, starring Wang Xi, Linda Chung, Raymond, Li Sijie, Zhu Huimin, King-Tan Yuen and Shi Xiu, and supervised by Kyle Law. It is not only a detective drama, but also a drama involving the supernatural. The detective's plot is a mixture of strange things. The case he encountered is not an ordinary case, but a strange case beyond reality.
