The Lunatics (Chinese: 癲佬正傳; Jyutping: din1 lou2 zing3 zyun6) is a 1986 Hong Kong drama film written and directed by Yee Tung-Shing in his directorial debut.

[2] A mentally ill man named Doggie causes a disturbance while playing at a fish market when the police think that he has taken a woman hostage with a cleaver.

Miss Lau, a Hong Kong journalist, observes this and becomes interested in the work of Mr. Tsui, a psychiatrist who donates his time to help the mentally ill, many of them living on the streets.

Intending to bring change from the government by raising public awareness of the issue of inadequate healthcare for mentally ill people, Miss Lau writes a story for the newspaper about Tsuen's routine of breaking the necks of chicken but was refused care at the hospital as he wasn’t deemed a risk.

Mr. Tsui's patients and acquaintances attend his funeral, after which Miss Lau begins looking after the mentally ill on the streets of Hong Kong.

"[4] In his book A Different Brilliance: The D&B Story, author Po Fung wrote, "adopting a social realist approach, The Lunatics offered a gritty portrayal of the dismal living conditions of one of the most marginalised groups in Hong Kong known as the mentally ill."[5]
