Guan Yu chose Liu Bei as his comrade and leader, held high the banner of supporting Han, worked hard, risked his life, was unyielding and poor, and gave all his strength and life to practice his chosen cause of supporting Han and resisting Cao.
The battle of the Three Kingdoms is actually a contest between justice and ambition, loyalty and conspiracy. At that time, most historical figures were not sure about their rebellion, but pursued realistic interests and personal future. Guan Yu chose a just cause (that is, the political and social order that Confucianism yearned for) and did not hesitate to die; I chose like-minded comrades, and I will never die. He became sworn in with Liu Bei and Zhang Fei in Taoyuan, and forged a lifelong friendship of brothers, the meaning of Guan Yu.
Benevolence is the political ideal of Confucianism and the political pursuit of Guan Gong all his life. Following Liu Bei is mainly for Liu Bei, a generous, kind and kind leader. Opposing Cao Cao is mainly because of Cao Cao's ambition to usurp the Han Dynasty and the cruelty and tyranny of killing cities at every turn. Guan Gong and Liu Bei's team have never killed innocent people or soldiers, and they will never give up protecting the people in any emergency.
Guan Gong's bravery will go down in history forever and be praised by people. Scraping bones to cure poison, the world praised its perseverance; Going to the meeting alone, the world praises its fearlessness; Riding alone to protect her sister-in-law, she found her brother thousands of miles away, and the world praised her for her strength. Hanjin saved the defeated army, Jiangbei blocked Li Tong, and Ni Qing refused to enter. Stationed alone in Jingzhou, facing Cao Wei and Dongwu two major military groups. He is the commander-in-chief and a brave soldier.
