Review of the confusing Tsinghua female student poisoning case! What happened next?

Tsinghua University and Peking University have always been the halls of desire for countless students. For students, if they can get into Tsinghua University, a bright future awaits them.

Many years ago, a thallium poisoning incident occurred at Tsinghua University. Over the years, there has been no conclusion. Today, everyone is invited to follow the author and peel off the cocoons together to explore the truth behind the incident.

Zhu Ling was born in Beijing in 1973. His parents were intellectuals and his family was well off. When he was young, Zhu Ling showed great talent. He was very smart and eager to learn, and his grades were among the best.

In addition to excellent academic performance, Zhu Ling has many talents. Not only is he proficient in the piano, but he is also good at playing the guqin. This shows that Zhu Ling is really outstanding.

Zhu Ling once had an older sister named Wu Jin, who was once a top student at Peking University. However, she unfortunately fell off a cliff and died during a spring outing in April 1989.

After that, Zhu Ling was the only one left in the family. The parents concentrated all their love on Zhu Ling. Zhu Ling, who had high hopes from his parents, did not disappoint them.

In 1992, Zhu Ling was admitted to Tsinghua University with excellent results. As everyone knows, bad luck is waiting for Zhu Ling ahead, which will deal a serious blow to the family.

On November 24, 1994, Zhu Ling suffered a sudden severe pain in his stomach. Within a few days, all his hair fell out. Afterwards, Zhu Ling was hospitalized for treatment.

After treatment by doctors, Zhu Ling's symptoms were temporarily relieved, but the cause could not be diagnosed. The following year, Zhu Ling returned to school again, but his condition relapsed again.

On March 9, 1995, a hospital professor suspected that Zhu Ling’s symptoms were thallium poisoning. However, Zhu Ling denied a history of exposure to thallium. Since the hospital did not have thallium testing equipment, it was never tested.

As time went by, Zhu Ling's condition gradually worsened, seriously threatening his life safety. When the students heard about Zhu Ling's condition, they spontaneously translated it into foreign languages ??and sent it to all over the world.

Of the 3,000 replies that followed, about one-third believed that Zhu Ling was poisoned by thallium. After that, relevant experts tested Zhu Ling again.

It was determined that Zhu Ling was suffering from thallium poisoning because the thallium content in Zhu Ling’s body was much higher than the lethal dose. Therefore, experts suspect that someone deliberately poisoned it.

Afterwards, Zhu Ling’s parents went to Tsinghua University to report the incident, and the public security organs opened a case for investigation. However, a rather dramatic scene occurred.

During the May Day holiday, a theft occurred in Zhu Ling's dormitory. What is puzzling is that only Zhu Ling's personal belongings were lost, and his roommates in the same dormitory did not lose anything.

After some investigation, the police found that no more than 200 people in Beijing could be exposed to thallium. Therefore, it is bold to speculate that Zhu Ling was poisoned by others.

After some investigation, the police focused their suspicion on Sun Wei. Sun Wei was Zhu Ling's classmate and roommate. At the same time, Sun Wei's father and Zhu Ling's father both worked in the same unit.

According to insiders, there are four people living in Zhu Ling’s dormitory. On weekdays, Zhu Ling is very studious and often leaves early and comes back late. Therefore, the other three roommates became jealous and conspired to poison him.

On Sun Wei's suggestion, Sun Wei was responsible for taking the thallium, and the other two were responsible for poisoning. At first, the three people only poisoned him in small doses, which only caused Zhu Ling's physical discomfort.

After that, Sun Wei and others poisoned Zhu Ling again. In the end, Zhu Ling was tortured by the disease for the rest of his life. It used to be a bright future, but now it's a lifelong regret.

Now, Sun Wei has immigrated to the United States. As time goes by, there is no official conclusion on this matter.

After listening to this article, do you think what the insider said is true?
