Guan Yu was a very important general for the Shu state. However, in the twenty-fourth year of Jian'an, this important general of the Shu state died at the hands of Lü Meng of Eastern Wu. This year was both happy and sad for the Shu kingdom, and the joy was that Liu Bei finally took the land of Hanzhong after many years of entanglement with Cao Cao in Hanzhong. Sadly, Guan Yu heard the good news and began to attack Fancheng, and eventually died because of his pride.
Guan Yu's death was like a thunderbolt on a sunny day for the Shu kingdom, and Guan Yu's death had a lot to do with Meng Da's defection, and Liu Bei's eldest son Liu Feng could not resist Cao Jun and fled back to Chengdu. After experiencing the joy of the previous capture of Hanzhong, the generals of the Shu State immediately heard guan Yu's death, so their morale fell instantly.
After Liu Bei returned to Chengdu, he was very sad, and he was immersed in the news of Guan Yu's death all day long, and at this time Zhuge Liang said such a sentence to Liu Bei, which made Liu Bei make up his mind to put Liu Feng to death, which was: The seal is fierce and difficult to control. What this sentence shows is that although Liu Feng has now been suppressed by us, when all the people of the older generation of our Shu kingdom are dead, he is likely to compete with Liu Chan for the throne.
Although Liu Feng was Liu Bei's eldest son, he was not his own. His original surname was Kou and he lived in Changsha County. When he was young, his family changed and he grew up with his uncle. When he grew up, Liu Feng was adopted as a righteous son by Liu Bei because he was brave and proficient in eighteen martial arts. Such talents are also a blessing and a curse, at that time Liu Bei was already over sixty years old, and Liu Chan was still young.
Liu Feng already had a relatively high position in the Shu kingdom at that time, and such talented people were generally reluctant to submit to others. Then as long as he was a potential threat to Liu Chan in one day, Liu Bei, after hearing what Zhuge Liang said, directly found an opportunity to execute Liu Feng.
