Ying Zheng lived at the end of the Warring States Period, and the seven warring states men attacked each other excessively, and the people of all countries suffered the most. During the 800 years since the establishment of the Zhou Dynasty, the vassal states frequently attacked each other, from the first few hundred to the last seven.
People all over the world have suffered for hundreds of years, and they urgently need unity and stability. At this critical moment in history, Ying Zheng stepped forward, ended the war situation and established the Daqin Empire which unified the world.
This achievement can be said to be unprecedented, enough to shake the past and shine today. In the later period of governing the country, Ying Zheng unified the writing, unified the wheels, unified the weights and measures, and established the county system. Even now, we still benefit from these achievements. The Chinese nation is a big multi-ethnic family. Although the dialects are different, the characters are the same, which facilitates the cultural exchange and inheritance to some extent. In this regard, Ying Zheng made an immortal contribution.
In addition, he sent Meng Tian to drive out the northern Xiongnu, so the Xiongnu dared not go south to herd horses, and then built the Great Wall of Wan Li, which was equivalent to establishing a strong point for the Central Plains and greatly protecting the peace of the country. Although later generations criticized Ying Zheng for spending too much on people, the reality is that he has too many things to do and too little time for God.
Even if the Central Plains is in trouble, Baiyue's army can't turn back, which gives Liu Bang, Xiang Yu and others an opportunity, and a group of prisoners in Lishan can beat them like that. If Daqin Ruishi attacked, Xiang Yu and others would have lost an opportunity.
From this perspective, Qin Shihuang's contribution is definitely greater than his fault. In my opinion, it is indeed a luxury to build the imperial tomb, but it is precisely because of this that we have left the Qin Terracotta Warriors and Horses that can shock the world.
In a word, I think Qin Shihuang is a wise king.
