The Constable is a 2013 Hong Kong action drama film written, produced and directed by Dennis Law and starring Simon Yam.

Lam hires a girl named Lin Tsui-yan to watch Chung when he goes to work.

This made Tsui-yan's boyfriend, Chow Gong-hong feel uncomfortable.

After Chung's death, Tsui-yan still spent a lot of time at Lam's house.

During the patrol, Lam saw Gong-hong and Dah Kin's gang, who were about to rob the bank.
