More importantly, Qin Shihuang was not cruel. In the process of reunifying China, people have never killed a massacre. Yan sent someone to assassinate them. Zhao Guoren bullied their mother and son when Qin Shihuang was a child. Qin Shihuang only punished the culprit, but did not retaliate on a large scale. The princes and ministers of the six countries do not slaughter. Qin Shihuang did this and even led to his death. The ministers of the six countries immediately rebelled and destroyed the state of Qin. During the 37 years of Qin Shihuang's reign, no minister was killed unjustly, and all meritorious military commanders and all senior officials were given preferential treatment. Later generations said that Qin Shihuang was cruel, mainly because the Han Dynasty had been throwing dirty water on Qin Shihuang and cursing his reputation.
