Why did Lv Buwei commit suicide by taking poison immediately after receiving a 30-word letter from Ying Zheng?

Ying Zheng wrote a 30-word letter to Lv Buwei. After reading the letter, Lv Buwei committed suicide by taking poison. Because Ying Zheng asked Lv Buwei two questions in his letter, one was to ask Lv Buwei what contribution he made to the State of Qin. The second is to ask what contribution Lv Buwei has made to Ying Zheng. Just 30 words and two questions denied what Qin and Ying Zheng had done. This letter dealt a fatal blow to Lv Buwei, who was exiled to Sichuan. In the end, he chose to commit suicide by taking poison.

Lv Buwei was originally a businessman, but he was ambitious and wanted greater benefits, so he decided to go into politics. Lv Buwei's judgment of the situation and people is very accurate. He chose to help Ann's son return to the State of Qin, and his son was taken hostage in the State of Zhao. I also gave my favorite concubine to a stranger. Later, after different people succeeded to the throne, Lv Buwei made great contributions to nature and was awarded the title of Guanzhong.

When it was reused by Qin, it was very capable of assisting the monarch to govern the country. There is no need to rely on harsh laws, and many relatively easy measures have been taken to promote the economic development of Qin. In addition, Lv Buwei believed that he had made great contributions to winning the throne and Ying Zheng, and his position in the State of Qin was stable. When Ying Zheng's letter denies Lv Buwei's achievements, Lv Buwei is extremely unacceptable.

Although Ying Zheng always called Lv Buwei Guan Zhong when he was young. However, because mother is Lv Buwei's favorite concubine, she can't forget the relationship between Lv Buwei and her mother. However, with the gradual maturity of Ying Zheng's age and thoughts, the political opinions of Lv Buwei and Ying Zheng have been contradictory. It is believed that Qin is very powerful now, leading by moderate governance measures, while Ying Zheng is more radical and ambitious. Therefore, when personal affairs and business affairs conflict together, it is doomed to the end of Lv Buwei.
