An information error of the Four Gentlemen of the Warring States Period is that

Meng Changjun's mistake. The four gentlemen of the Warring States period are "Chun" and "He Xin". No one is perfect. Even the four gentlemen who were highly respected during the Warring States period ignored the wrong information. Meng Changjun's mistake was that he had no choice. His kindness made him choose to trust strange guests, which was a short trip and a long regret.
