First, when Liu Bei proclaimed himself emperor, Guan Yu's great hatred was not reported.
After Guan Yu's death, Liu Bei proclaimed himself emperor, and Liu Bei Guan Yu and Zhang Fei became sworn brothers. They agreed to be in Taoyuan at that time? Can't be born on the same day in the same year, but want to die on the same day in the same year? By this time, Guan Yu was already dead. In Zhang Fei's mind, he should avenge Guan Yu. His second brother Guan Yu should not have died in vain. He and his eldest brother Liu Bei should avenge their second brother Guan Yu together. They should unite all forces that can be United to destroy Dongwu and avenge his second brother Guan Yu.
Liu Bei proclaimed himself emperor, and Zhang Fei was angry and unhappy, but Zhang Fei could only silently agree because of his eldest brother's face. He didn't sign or object, which was the only thing he could do.
Second, Zhao Yun has been living in Liu Bei's dream of helping Han people.
Zhaoyun was originally a subordinate of Gongsun Zan. Because he could not be reused, and because Gongsun Zan committed suicide after defeat, Zhao Yun took refuge in Liu Bei. Zhao Yun followed Liu Bei out of Liu Bei's benevolence and righteousness, and more because Liu Bei's banner was to help the Han Dynasty. After all, as a ministry of the Han Dynasty, Zhao Yun didn't want to watch the Han Dynasty perish. He wants to help the Han Dynasty with his own abilities and support it with his own actions. Liu Bei has been working hard to restore the Han Dynasty, and Liu Bei's men have been working hard to restore the Han Dynasty. It is unacceptable for Zhao Yun to stand on his own feet and be king in the process of hard work. It is very bad for him to make wedding dresses for others at the end of his life.
When Liu Bei proclaimed himself emperor, Zhao Yun didn't support him, but there were too many people who supported him, so there was no way out. Zhao Yun, who is already old, knows that he can't change anything. He didn't sign or object, which was the only thing he could do.
Finally: Liu Bei has always dreamed of being an emperor, but the foundation is too weak. He has been recruiting people under the banner of helping the Korean family. His method deceived everyone except himself. I became an emperor because I was afraid that I would never have the opportunity to be an emperor again in my lifetime. He is afraid that he has struggled in vain all his life. He used his last ability to struggle to become an emperor and barely fulfilled his dream.
