I thought that the once sensational Zhu Ling poisoning incident at Tsinghua University was gradually forgotten by everyone as Zhu Ling passed away not long ago. Unexpectedly, Zhu Ling's father recently submitted an "Application for Investigation Supervision" to the Supreme People's Procuratorate, requesting "to supervise the illegal activities of relevant departments during the investigation of Zhu Ling's poisoning case, provide corrective opinions or inspection suggestions, and supervise It continues to investigate the case," which once again aroused everyone's attention and heated discussion.

In fact, people who have learned about Zhu Ling's poisoning incident before will sigh with sadness whenever this matter is mentioned. It can be said that this is a tragic story of a young girl withering due to jealousy.

Zhu Lingben is a grade 92 student majoring in physical chemistry and instrumental analysis in the Department of Chemistry at Tsinghua University. He suddenly fell ill while studying at school and was diagnosed with thallium poisoning in 1995. After , various investigations confirmed that the poison was caused by someone else, but the poisoner is still at large.

Zhu Lingben was born into a well-off family. Her father is a senior engineer at the National Seismological Administration, and her mother is a senior engineer at Ocean Corporation. She also has an older sister, Wu Jin (one sister takes her father's surname and the other takes her mother's surname). There is an online article "Zhu Ling Family Biography" that describes the sisters: "Both of them have their own merits, but they are both girls that everyone loves... The two sisters played together on the same piano, and the song they played at that time was The Waltz of Kittens and Puppies, their family was full of laughter at that time, and they were a fascinating and happy family. "If the life of this family develops smoothly, there will definitely be many stories related to happiness. It's a pity that God first gave this family a seemingly beautiful script, but later arranged a dramatic plot twist, which directly turned the story into a tragedy.

After Zhu Ling was admitted to Tsinghua University, he was assigned to the same dormitory as his former middle school classmate Sun Wei. This Sun Wei was later considered to be the person who could legally obtain thallium salts and get close to Zhu Ling. Sun Wei's family conditions are more favorable than those of Zhu Ling's family, and he belongs to a pure aristocratic family.

After entering college, Zhu Ling played the piano and guqin very well, and soon became a main member of the school folk orchestra. He won many awards in various competitions, and his academic performance was always among the best. In addition to his pure appearance, he belonged to A very popular goddess-like figure in the school.

When they were freshmen, Zhu Ling and Sun Weiben were good friends. Sun Weiben wanted to join the folk band, but he failed the exam and later joined the band on Zhu Ling's recommendation. But due to his average level, he is also an ordinary person in the band.

As roommates in a dormitory and in a folk band, I thought their friendship would be very deep. Unexpectedly, friction continued after that. Zhu Ling's mother, Zhu Mingxin, recalled that Zhu Ling once lamented that it was difficult to maintain the friendship between good friends. Sun Wei often stumbling upon Zhu Ling without warning, causing Zhu Ling to be misunderstood by teachers and classmates.

In November 1994, Zhu Ling, a goddess-like figure, suddenly fell ill with a strange illness. She was sent to the hospital because of unbearable stomach pain, which was also accompanied by symptoms of massive hair loss. After seeking medical treatment for a period of time, his condition gradually showed signs of improvement, and Zhu Ling returned to school to continue his studies. However, in March 1995, she once again sought medical treatment for a "strange disease", and this time her symptoms were much more severe than the last time. Zhu Ling's high school friend Bei Zhicheng sought help remotely to find the cause of Zhu Ling's sudden strange illness. Among the many letters for help, 30% responded that they suspected thallium poisoning. At this moment, the keyword "thallium poisoning" was put on the table, and after testing by Professor Chen Zhenyang, a researcher at the Beijing Institute of Labor Protection and Occupational Diseases, it was confirmed that Zhu Ling was indeed thallium poisoned, and had been poisoned twice. The second time The thallium content in Hou Zhuling's body far exceeded the lethal dose.

Since thallium is something that is difficult for ordinary people to come into contact with, Zhu Ling suddenly suffered from thallium poisoning, and various clues pointed to the cause of "poisoning". According to the understanding of ordinary people, when encountering this kind of thing, we will definitely report the crime and start an investigation.After Zhu Ling's father learned that his daughter had been poisoned, he immediately contacted the school security department and asked them to seal off the dormitory to protect the scene. However, after Zhu Ling's father contacted the security department, a theft occurred in Zhu Ling's dormitory, and all Zhu Ling's daily necessities were lost. . After

, Sun Wei, who had the opportunity to come into contact with thallium and had an intersection with Zhu Ling, was identified as the only suspect in the case. However, later due to insufficient evidence, Sun Wei was ruled out as a criminal suspect.

As a result, the poisoning case became an unsolved case.

On December 22, 2023, Zhu Ling, who was paralyzed and had cranial nerve damage due to thallium poisoning, died in Beijing. Until now, the thallium poisoning case is still unresolved. The other heroine in this case, Sun Wei, has settled in Australia.

Now, Zhu Ling's father Wu Chengzhi submitted an "Application for Investigation Supervision". He expressed that he was concerned about Sun Wei's current situation, wanted to find out the matter, and said that he would not forgive the murderer.

This incident has made many people sigh for two reasons. First, everyone is unwilling to accept that the murderer is still free. Second, everyone has discovered that jealousy can really change a person beyond recognition, and he will not hesitate to kill his former friends.

Whenever everyone discusses this case, one topic will be mentioned: poisonous friendship.

As the saying goes, "Rely on your parents at home and rely on your friends outside." Many people value their friends and care about the friendship between people. However, they do not know that the troubles caused by making wrong friends are endless.

Therefore, many parents will also tell their children Zhu Ling's story, hoping that when making friends, their children must pay attention to distinguish which friends are worthy of making friends and which friends are not worthy of deep friendship. After all, in the world of children, they always think that friendship is a very pure and beautiful thing. They have not experienced the evil in the world, and they do not know that when friends become jealous, stories about "evil" begin. Only by not being jealous of others and staying away from jealous people can we better protect ourselves.
