Sister-in-law is a suspense crime film produced and written by Jing Wong, directed by Kan Jiawei and starring Zhang Jincheng, Lacker and Philip Ng.

The film tells the legendary story of Zuo Lan, an ill-fated girl, who fell into the whirlpool of love and crime step by step after encountering Tian Tao, an iron fist, and was promoted to become a Jianghu sister during the colonial period of Hong Kong and Britain. The film was released on February 7, 20 17.

Three highlights of Sister-in-law: First, in the film, the scenery of Jiulongzhai Town surprised thousands of audiences, and the cramped alleys, messy shops and dimly lit drug abuse places seemed to reproduce Hong Kong in the 1970s in front of the audience; Aspect 2: Raquel turned into a black rose and Zhang Jincheng re-formed the strongest CP; Aspect 3: the supporting role of the unknown "old play bone" is worth calling.

Sister-in-law is full of blood and violence, revealing the selfish weakness of human nature in the film. In "The Old Days of Gunfire in Hong Kong", Zuo Lan, the heroine, retired from a pure girl to a Jianghu sister-in-law, showing a Jianghu full of joy and hatred, and made a thrilling Jianghu sister-in-law.
