After Mr Qin’s disappearance, rumours swirled about his possible imprisonment, suicide, and an extramarital affair with a Chinese journalist, Fu Xiaotian, which might have posed a security risk.

Detective Chinatown 1900 is one such cinematic endeavor. Set in San Francisco in 1900, the film follows detectives Qin Fu and Ah Gui as they investigate the murder of an American woman in Chinatown.
