What are the tragic events in history?

Personally, I feel that Qin Shihuang's book burning incident had a great influence at that time, which was a retrogression of culture and was particularly bad at that time. Moreover, Qin Shihuang was probably trying to consolidate his rule at that time, so I think he would let people burn books to bury Confucianism. So did Qin Xiaogong, the grandfather of Qin Shihuang, and the scale of Qin Shihuang's burning books was bigger than his grandfather's, but it was not like the textbook said, except Qin State.

At the suggestion of Li Si, the prime minister of Qin at that time, Qin Shihuang not only burned poems, books and hundreds of languages, but also hid the History of Six Kingdoms, that is, the historical records of governors. And I burned all the works of divination, medical care, farming and pre-Qin philosophers, so I think what he did at that time was really excessive and bad.

Qin Shihuang's bullying of Confucianism is a disaster that many literati have suffered, so I think these are really bad, and Qin Shihuang is also a tyrant, so I think these are very bad, and there are many very violent things. Not only that, he also has other bad things, such as his building in Daxing, so I think this is very bad, which makes people suffer, so I think it is very bad.

And there are many things that hurt the scholar, and there are other things that make the people miserable and let the people build their tombs for many years, so I think he is very bad, not a monarch, but a tyrant. Many of his work styles are cruel, so I think I should do my own thing.
