The Qin dynasty did not engage in literary inquisition, but banned books to fool the people, but books were only burned among the people, and all the materials were stored in the palace. Only later, after Xiang Yu entered Xianyang, a fire destroyed the palace with books. The reason is that Liu Xiang didn't study and didn't know the value of books. Later generations cannot blame Xiang Yu's failure on him, but simply on Qin Shihuang. The reason why Qin Shihuang held a meeting to ask intellectuals for advice was that they didn't say it in person, but agreed. Qin Shihuang was very angry after hearing the report, and ordered to punish a dozen people who said trivial things according to law. In order to protect themselves, those people rushed to implicate others and found out hundreds of people at once. The first emperor was furious and ordered the killing of these people. The prince remonstrated with Qin Shihuang, but angered Qin Shihuang and was driven to the north to guard the Great Wall. The scholar's bad habits were already shown at that time.
