In the Three Kingdoms, Liu Bei was able to dominate the throne, and what he relied on was his ability to recognize people, such as Zhao Yun, who was not reused under Gongsun Zhan at that time, was discovered by Liu Bei, and later proved that Zhao Yun was indeed a useful person. However, liu bei often saw countless people right in his life, but he once looked at three people wrongly, one was strong in force, and one was wise and better than Zhuge Liang.
First: Lü Bu
In 195, Lü Bu was defeated by Cao Cao, and Lü Bu, who had nowhere else to go, had to defect to Liu Bei. At that time, Liu Bei saw that Lü Bu had nowhere to go and took him under his door, but Liu Bei seemed to forget that Lü Bu was a shameless person. Yuan Shu was already dissatisfied with Liu Bei's occupation of Xuzhou, so he sent troops to attack Liu Bei.
At that time, after Liu Bei learned of this, he immediately led his army to block the attack, leaving the land of Xuzhou, which was insufficient, to Lü Bu. As soon as Liu Bei left, Lü Bu turned around and took Xuzhou for himself, and in the end Liu Bei could only choose to defect to Cao Cao.
Second place: Mi Fang
Mi Fang's family was kind to Liu Bei, and all the money used by Liu Bei to establish an army came from Mi Fang's family. Liu Bei was very grateful to the Mi family, and even married Lady Mi through the door. Mi Fang's younger brother Mi Lan was also highly valued because of his relationship with Liu Bei and became the Taishou of Nan Commandery. However, Mi Lan did not resist the pressure at the critical moment, and finally fell without a fight, resulting in Guan Yu's death on the battlefield. If Liu Bei had not been nepotistic, Guan Yu would not have died at the hands of Lü Meng.
Third place: Pang Tong
When Pang Tong first defected to Liu Bei, Liu Bei did not reuse Pang Tong, and the reason was very simple, Pang Tong's appearance was too ugly. However, Pang Tong was introduced by Zhuge Liang after all, so Liu Bei only gave a small county official. If it were not for Zhuge Liang's strong request for Liu Bei to use Pang Tong, I am afraid that Liu Bei would not have known that he had such a powerful person under his command, and in the end Liu Bei's famous attack on Yizhou was bought by Pang Tong with his death.
