In fact, Zhang Yi's death has not been interpreted too much, which is a normal death. Because of Zhang Yi's outstanding contribution, King Huiwen of Qin named him "Wu Xinjun" and named him five cities. Zhang Yi's skill of Lian Heng became the basic strategy for Qin to destroy six countries and unify the world.

After the death of King Hui of Qin, Qin Wuwang, who acceded to the throne, didn't like Zhang Yi when he was a prince, so Zhang Yi fled Wei and became, and died a year later. For a counselor like Zhang Yi, what saddens him most is that others don't adopt his advice. After Qi ignored him, Zhang Yi seemed to have a heart attack and died a year after Wei, which was the final outcome of this kind of adviser.

Zhang Yi's achievements:

With a golden tongue, the six countries were turned into pro-Qin Lian Heng, which laid the foundation for Qin to destroy the six countries and unify the world. During the Warring States period, the strategists lobbied around with their golden tongue, which can be described as "falling in love with the country". One of the most prominent figures is Zhang Yi who advocates "Lian Heng".

According to records, Zhang Yi mastered the housekeeping skills of strategists at a young age. After many twists and turns, he came to the state of Qin, was appreciated by King Hui of Qin, and was named Prime Minister. Later, Zhang Yi went to various countries to tease the governors of the world with his golden tongue. First, he broke the alliance between Qin and Qi, and then he went to Qi, Zhao and Yan to persuade the governors of various countries to "unite" and pro-Qin. In this way, the "vertical" alliance of the six countries was finally broken up by Zhang Yi.
