According to NDTV, he tried to alleviate his girlfriend's insomnia with frequent injections of anaesthesia, which ultimately led to her death. She died after he gave her the anaesthetic over 20 times in six hours. Many Chinese internet users have taken to criticizing the doctor's behaviour in response to this occurrence, even though he has stated that he is only attempting to help.

Notably, in the summer of 2022, the two connected via an internet dating service. Between September 2023 and March 2024, the accused who works at a hospital in Jinjiang County, Leshan, is accused of repeatedly giving the woman the potent anaesthetic propofol in a hotel room. The accused claimed that his partner sought the help of the drug to help her insomnia, reports the Daily.

On March 6, the accused administered about 1,300 mg of propofol via her ankle over six hours, from 11 p.m. to 5 a.m. He gave her more than 20 dosages and then another 100 mg to use at a later time. When he got back to the motel, he found his girlfriend dead. Acute propofol intoxication was determined to be the cause of her death by a medical assessment.

According to the Daily, the doctor quickly informed the authorities about the accident, admitted his guilt, and then paid her family 400,000 yuan (US$55,000) in compensation, after which they forgave him. The Anaesthesiologist was found guilty of negligent homicide and he was sentenced to two and a half years in prison by the People's Court of Renshou County in Sichuan Province on November 1. His voluntary surrender to the authorities, his confession, the victim's family's lenient attitude towards him, and monetary compensation were all considered by the court as important mitigating factors.
