In August, 1985, human residual limbs were found at Heisha Beach in Macau. Sir Li (Li Xiuxian) of the Macao Ministry of Justice, a major crime unit of the police, began to investigate the case and found that all the Zheng family in the Eight Immortals Hotel disappeared overnight. When the police went to investigate, Wang Zhiheng (Huang Qiusheng), the head of the Eight Immortals Hotel, said that the Zheng family had emigrated overseas and gave him the top of the hotel. Later, Sir Li found that the Zheng family had no exit record and waited for an opportunity to arrest Wang to assist in the investigation. Wang attempted to sneak back to the mainland and arrested him. During his detention, Wang not only refused to cooperate and concealed the facts, but the Ministry of Justice tried every means to force him to confess, while Wang attempted to commit suicide and confront the judiciary in prison. Finally, forced by torture, Wang finally confessed the murder, but Wang eventually cut his wrist and didn't want to face up to 24 years in prison.
