Her Fatal Ways is a 1990 Hong Kong crime-comedy film. It is directed and written by Alfred Cheung Kin Ting and stars Carol "Dodo" Cheng, Tony Leung Ka-Fai, Sunny Fang Kang, Michael Chow, Sheila Chan and the Director himself. The film won the 10th Hong Kong Film Award for the Best Actress.

This film takes place in Hong Kong, where Mainland Chinese MPS officer Cheng Shih-nan (Cheng) extradites drug-dealer Wong Ti (Chow) to the Royal Hong Kong Police. Wong escapes and Cheng is forced by the State Council to stay abroad in Hong Kong and assist Chief Inspector Wu Wei-kuo (Leung) to track down Wong, as well as his boss, So Kuo Jung (Fang). The cultural differences between Hong Kong and Mainland China and her rivalry with Wu's father, a former military officer of Kuomintang, become a big headache for Cheng, a loyal member of the Chinese Communist Party.
