What contributions did Guan Yu have, and what did Guan Yu do before

For Cao Cao, Guan Yu helped him kill Yuan Shao's fierce generals Yan Liang and Wen Chou, relieve the siege of White Horse, and release Cao Cao in Huarong Daoyi;

For Liu Bei, he traveled thousands of miles to escort his sister-in-law, guarded Jingzhou, flooded the Seventh Army to break Cao's army, and went to the meeting to establish the prestige of Shu Han.

The biggest contribution is that there is a god position, and everyone knows that Guan Erye has received folk incense.

Big credit: 1. Fight with Xu Huang against Yan Liang, and Yan Liang was killed (note, with Xu Huang).

2, confronted Yu Ban, but unexpectedly, the river water swelled and there was a flood (note that the river water surged), Yu Ban lacked knowledge of flood control, the Seventh Army was flooded, and Guan Yu took the opportunity to clean him up.

3. After flooding the Seventh Army, Guan Yu bribed the local forces in Henan and let them make trouble, so that Cao Cao wanted to move the capital to avoid the limelight (I personally think this is his best action).

Didn't going to the meeting alone help Liu Bei a lot?

Guan Yu's historical merits are:

After Liu Bei got Xuzhou, he made Guan Yu too guarded. In the fifth year of Jian'an, Cao Cao marched eastward, defeated Liu Bei, Guan Yu was captured, and then followed Cao Cao to meet Yuan Shaojun in Guandu, assassinated Yuan Shao's general Yan Liang in the crowd, sealed the Marquis of Hanshou Pavilion, and soon resigned to Liu Bei. Later, Liu Bei attached himself to Jingzhou Mu Liu Biao.

In the thirteenth year of Jian'an, Cao Cao entered Jingzhou, Liu Bei led the people to flee south, and Guan Yu went to Xiakou with him. and Cao Cao was defeated in Chibi, Liu Bei collected the counties south of the Yangtze River, and appointed Guan Yu as the general of Xiangyang Taishou and Dangkou. Liu Bei set Yizhou in the west and made Guan Yu guard Jingzhou.

In the 20th year of Jian'an, Guan Yu expelled the magistrates of Changsha, Lingling, and Guiyang counties placed by Sun Quan. In the twenty-fourth year of Jian'an, worship as a former general, besieged Cao Cao's general Cao Ren in Fancheng, when the Han River flooded, General Zuo supervised the seven armies in the forbidden place were submerged, and beheaded the general Pang De, since the south of Xu often responded remotely, and shocked China.

Guan Yu's early experience:

In his early years, he fled his hometown and went to Zhuo County, Youzhou, because of his crimes, and in the first year of Zhongping, the Yellow Turban Rebellion broke out, and Liu Bei organized a volunteer army in Zhuo County. Guan Yu and Zhang Fei all joined them, and traveled around with Liu Bei to participate in the war to extinguish the Yellow Turban Army.

When Liu Bei served as the minister of the plains, he appointed Guan Yu and Zhang Fei as the Sima of other departments and divided the divisions. When Liu Bei attended the event, Guan Yu and Zhang Fei stood by Liu Bei's side to protect Liu Bei.

Guan Yu turned out to be a small trader selling dates.

Guan Yu's profession is not mentioned in the Romance of the Three Kingdoms, Guan Yu fled his hometown to Zhuo County in Youzhou in his early years due to crimes, and sold dates on the way to escape.

Guan Yu was a famous general in the late Eastern Han Dynasty. When Liu Bei raised his army, Guan Yu followed Liu Bei, was loyal, and was deeply trusted by Liu Bei. Liu Bei, Zhuge Liang and others entered the Shu State, Guan Yu guarded Jingzhou, after Liu Bei seized Hanzhong, Guan Yu took advantage of the situation to attack Wei in the north, and had besieged Xiangfan, captured Yu Ban, beheaded Pang De, and shocked Huaxia, the Central Plains was shaken, but the Eastern Wu sneak attack Jingzhou, Guan Yu was defeated and killed.
