The above shows that Qin Shihuang was an emperor who made great contributions to the history of our country and had great influence. But he was also a cruel feudal emperor. He built a large number of palaces and tombs, which wasted a lot of manpower, material resources and financial resources and affected people's normal production and life. He also enacted a cruel criminal law, which made people live in dire straits; He burned books to bury Confucianism, stifled ideas and destroyed culture.

He was the first emperor of China, and he claimed to be the first emperor. He also stipulated that the descendants who succeeded to the throne should be arranged in order. The second generation is called Emperor II, and the third generation is called Emperor III. This is handed down from generation to generation and passed on to the next generation.

He abolished the enfeoffment system and changed it to the county system, dividing the country into 36 counties, and then dividing them below. The county magistrate was appointed directly by the court. The political affairs of the country, big or small, are decided by the emperor.

After Qin Shihuang unified the Central Plains, he sent a general, Meng tián, to lead 300,000 troops to resist, and incorporated all the areas around the Hetao, setting up 44 counties. In order to resist the invasion of Xiongnu, Qin Shihuang recruited civilian workers, connected the original northern walls of Yan, Zhao and Qin, and built many new walls. In this way, from Lintao (now Min County, Gansu Province) in the west to Liaodong (now Northwest Liaoyang, Liaoning Province) in the east, the Great Wall of Wan Li is connected together. This world-famous ancient building has always been a symbol of our ancient Chinese civilization.

Later, Qin Shihuang sent 500 thousand troops to pacify the south and set up three counties; The following year, Meng Tian defeated the Huns and added another county. So there are 40 counties in China.

In 2 13 BC, Qin Shihuang held a celebration banquet in Xianyang Palace for opening up territory. Many ministers praised Qin Shihuang's achievements in unifying the whole country. Dr. Chun Yuyue, however, reiterated that the enfeoffment system could not be abolished, and he thought it would not work if he did not follow the ancient rules. By this time, Reese had become prime minister. Qin Shihuang wants to hear his opinion. Reese said: "Now the world is stable and the law and discipline are unified. However, a group of scholars do not study the present, but study the ancient times, making wild comments on state affairs and creating confusion among the people. If it is not prohibited, it will affect the prestige of the court. " Qin Shihuang adopted Lisi's idea and immediately gave an order: except for books such as medicine and planting trees, all books containing poems, books and hundreds of speeches were handed in and burned; Whoever talks privately about such books again commits the capital punishment; Anyone who criticizes the present with the ancient system will be beheaded. In the second year, there were two alchemists (people who swindled money from an alchemist) named Lu Sheng and Hou Sheng, who talked about Qin Shihuang behind his back. When Qin Shihuang learned of this situation, he sent people to catch them. They have escaped. Qin Shihuang was greatly annoyed. He checked again and found that some Confucian scholars in Xianyang were also talking about him together. Qin Shihuang arrested those Confucian scholars for interrogation. Confucian scholars can't stand the torture and give up a large number of people at will. Qin Shihuang ordered more than 460 Confucian scholars who violated the ban to be buried and the rest exiled to the border. This is the event of "burning books to bury Confucianism" in history. Qin Shihuang was so angry that no one dared to persuade him. His eldest son, Fu Su, thought it was too harsh to deal with Confucian scholars and advised him not to do so. Gal, angered Qin Shihuang, ordered Fu Su to leave Xianyang and go to the north to guard the border with Montaigne.
