Six States Installation of Minister murder

On 5 November 1951, Chu Shing-choi went back to his former residence at No. 359 Lockhart Road to collect his properties. At this time, three women denounced him for taking up valuable space in the house, and an argument ensued. Chu then immediately went into the kitchen, took out the butcher's knife, and locked the main doors to the house.

Before he assaulted his sister-in-law, Chu Shing-choi said "You wanted see my rendition of "Six States Installation of Minister", did you? I have been prepared a long time ago, and I already bought this knife for a month now. I will kill all today!" (Chinese: 你們不是渴望看我的《六國大封相》嗎？我早已準備好，這把刀也給你們買下個多月了，今天我就要大開殺戒！)

After that speech, Chu struck his sister-in-law with the butcher's knife. She was struck in the head and both arms. As Guan Yue-E rushed out of the house for help, Chu rushed into Guan Yue-E's room, and killed Wong Siu-lun, Yue-E's three-year-old daughter. Chan Chiu also tried to escape, but failed, and was murdered as well. As for the maid, Wong Mei, she was seriously injured.

After the murder, Chu took out the can of petrol he bought earlier, and poured it around the apartment and set it on fire. While escaping, Chu encounted Wang Zi-Xiang's son of age four, named Wong Shiu-young. Zhu grabbed the young Wong and threw him out from the 4th floor apartment, resulting in heavy injury for the boy. Despite the fact that a crowd had gathered, Wong wasn't stopped by the crowd due to believing he was merely escaping the fire.

• Murdered: 3; Chen Chiu, Guan Yue-E, and Wong Siu-lun
• Injured: 3; Guan Yue Mei, Wong Mei, and Wang Zi-Xiang's son Wong Shiu-young

The other renters were not in flats at the time.

Due to the damages and casualties, the murder attract much sensations among Hong Kong news media, while the police had set up blockades to prevent him leaving Hong Kong.

On 8 November 1951, at 6:50 am, Chu surrendered to the police at Central Police Station. During body search, it was discovered that he only had one Hong Kong dime, three handkerchiefs, and a letter addressed to the police and news media.

In the letter, Chu laid out the motive and incident of the murder, as well as expressing his displeasure of the motive guessed by the news media, which wrongly reported his motive was due to failure to borrow money. In it, he stated that due to cynicism and scoldings from the women in the flat, he had planned to burn down the house and do nothing else; the murder was incidental caused by the women in their attempt to prevent the arson. He also stated that he greatly hated Guan Yue Mei, who had chased Wang Qi Wen away from him. He further confessed that he had planned to kill himself by jumping out of the flat's window, but due to the gathering crowd on the street he chose escape instead. He had attempted to hide with his girlfriend and friends, but due to the heavy reporting, none of them was willing to hide him, and thus he chose to surrender to the police.

The court decided to try Chu only on one count, of the murder of Chen Xiao; it was common for the then-Hong Kong Judicial branch to focus on trying the most hindeous crime in order to minimise usage of Judicial resources, since if he was guilty on the charge of premeditated murder, he would be given death penalty. During the Trial, the defence attempted to use insanity caused by provocation, but prosecutor pointed out that the psychiatric reports showed the accused does not have any mental issues; furthermore, prior to the murder, the accused had prepared the instruments of murder, and had purposely locked the door, which showed that it was a deliberate, planned crime, and that the accused was not insane nor diminish during the moment of murder. Due to this, the jury delivered a guilty verdict to Zhu Sheng Cai on one count of murder, and was sentenced to be hanged on 23 May 1952.
