In ancient times, the emperor was the supreme being. As the saying goes, companions are like tigers, so it is very important to straighten yourself out in the court. In the history of our country for thousands of years, there are many people who have made great achievements in the country. They should have enjoyed preferential treatment, but in the end they were crowned with success and ended in tragedy because they didn't put their position right.
For example, Tian Lei is a very famous strategist. Together with Lian Po and others, he was known as the Four Great Generals of the Warring States Period. The famous battle of Changping was won, and later hundreds of thousands of Zhao troops were killed in the pit. He was called the human massacre. Because of his outstanding military exploits, he was later incorporated into the Wu' an Army. However, since the battle of Changping, the emperor did not listen to dissuasion and rushed to send troops, which eventually led to a fiasco, but the blame fell on Tian Lei.
Han Xin, one of the three outstanding heroes of early han dynasty, made a lot of exploits after following Liu Bang, and was named King Huaiyin, and got a lot of rewards. However, because he was too powerful, the emperor worried that he would rebel, and finally died under the calculation of the emperor and Xiao He. There is also a generation of famous Nian Gengyao, a benefactor of Yong Zhengdi, who has made great contributions to Yong Zhengdi, but later he became arrogant and domineering, which offended many people and ended badly. Guo Ziyi once made great contributions to the imperial court, but later he was often framed by treacherous court officials.
