First of all, I don't think it's necessary to criticize Wei too much, because it's too common that talented people are not reused in the history of China. For example, Wu Zixu, Wen Zi and Fan Li were all Chu people when they competed for hegemony in wuyue, Zhuge Liang was already within the jurisdiction of Liu Biao when he was in the Three Kingdoms, and Pang Tongxian sought audience with Sun Quan first. These examples can prove the universality of this phenomenon, and the reason is nothing more than the wise degree of the monarch and the national talent selection system.

In addition, the use of Qin was very common in the seven countries during the Warring States period, which showed that the social and cultural customs and officialdom atmosphere at that time were very active, with a high degree of freedom and a low degree of imprisonment of scholars' thoughts and behaviors. The mainstream thought highly praised talents, which reflected from the side that it was an era of low centralization, relatively free personality and a hundred flowers of cultural thought.
