[1] On May 23, 2019, The First Intermediate People's Court of Shanghai [zh] decided that Huang's mental illness did not affect his ability to control his own behavior.

[7] At 11:31 a.m. on June 28, the Xuhui Branch of Shanghai Municipal Public Security Bureau received a phone call, saying that a man with a kitchen knife had cut three boys and a female parent near the sidewalk of Guilin West Street[note 1] on Pubei Road.

[citation needed] With the help of others at the scene of the attack, the police arrested Huang Yichuan, the assailant, and sent the injured victims to the hospital.

[9] According to a number of netizens, the site of the attack was found to be near the gate[3][9] of the West Campus of the Shanghai World Foreign Language Primary School [zh].

[10] A number of people at the scene, including the staff of city management, held Huang Yichuan down to prevent his escape, and a passing air conditioner repairman tied him up with a rope.

[9] One of the students, known only as Tan, was confirmed to have died from injury to the central nervous system and hemorrhagic shock due to the stabbing.

[5] According to an examination of the First Branch of Shanghai People's Procuratorate, the criminal suspect, Huang Yichuan, male, was unemployed at the time of the attack.

On the morning of June 28, he set out from his hotel with a stainless-steel kitchen knife and took a bus to Guilin West Street near the World Foreign Language Primary School.

A month before the Pubei murders, Huang Yichuan took the train from Guangzhou to Shanghai, spending most of his time at a youth hostel in the Pudong New Area.

During the trial, the procuratorate recommended the court to punish him according to the provisions of the third paragraph of Article 18 of the Criminal Law of the People's Republic of China.

In the judgment, the First Intermediate People's Court of Shanghai pointed out that Huang Yichuan decided to kill primary school students in order to vent his anger because he "thought he was being bullied and hurt by others."

Although Huang Yichuan has schizophrenia and, therefore, had limited criminal responsibility, his crime was extremely serious, and the court decided that his mental illness did not affect his ability to control his behavior in this case.

However, the procuratorial organ believed that the facts of Huang Yichuan's homicide were clear, the applicable law was correct, and the trial procedure was legal, meaning that his sentence was appropriate.
