Ask for an article, a Liu Qingyun Hong Kong film, where he can see other people's ghosts. What's it called?

The title of the film is Detective, which is directed by Du Qifeng and Wei Jiahui. Wei Jiahui is in charge of the script. On September 5th, 2007, at the 64th Venice International Film Festival, it premiered as the last surprise film. The film is set in the Hong Kong police. The hero, Chen Guibin, is a retired policeman with schizophrenia and lives in seclusion with his wife, Zhang Meihua. Chen Guibin used to be a genius who never solved a case, so He Jiaan came to consult his old boss to handle a special case. The theme is similar to that of the police and bandits films he is good at, but he thinks that Du's films are newer and more in-depth than before. Du Qifeng and Wei Jiahui have worked together for many years. Since 2003, "Detective" is a film they have collaborated on more than in 2006.
