What changes in the government of the country took place under Qin Shihuang?

It was Qin Shi Huang who succeeded in uniting China. Under the leadership of this emperor (Qin Shi Huang Ti became the first emperor of China), they began to build the famous Great Wall of China, and the Terracotta Army also entered his service, and even today it remains the most famous symbol of China. True, in addition to his merits, he was a cruel dictator, whom too many subjects did not like. As soon as the emperor died, the Qin dynasty was quickly overthrown by the rebellious people, who were getting tired of the terror perpetrated by the reformer.
