How to write the reasons for liking Guan Yu?

I like Guan Yu because he was in America a long time ago and he was very loyal. In the seventh chapter of Romance of the Three Kingdoms, he killed six generals of Cao Cao in succession to protect Liu Bei's wife and children. Even so, Cao Cao advised Guan Yu to surrender to himself several times, but Guan Yu was loyal and refused again and again. But in the most critical time of Cao Cao, Guan Yu killed two generals, Yan Liang and Wen Chou, for him. This shows that Guan Yu is really a brother who values affection and righteousness.

Unfortunately, a hero like Guan Yu was cornered in Chapter 20. Guan Yu and his son were captured alive by Sun Quan, who saw that he would rather die than surrender. In desperation, they had to be beheaded. A generation of heroes gave their lives for love and justice.

Guan Yu has been honest since he was a child. Later, he killed a bully and was chased by the government, so he had to take refuge in a foreign country. Since then, I have never been back to my hometown to see my parents. But I think his parents will be extremely proud of having such a son. After Guan Yu's death, Cao Cao buried Guan Yu and his son in the south gate of Luoyang, and personally led a hundred civil and military officials to pay their respects. Cao Cao did this because he was moved by Guan Yu's great love and righteousness.
