First, Liu Bei is virtuous and cannot be said to be unfilial.
The novel Romance of the Three Kingdoms was originally about the ugly States of Wei and Wu in Shu, and Liu Bei will naturally become the number one hero of the Three Kingdoms. Luo Guanzhong also praised Liu Bei to the sky, but if you want to say that Liu Bei is unfaithful, unjust and heartless, then you will completely blacken Liu Bei! Liu Bei served others with virtue in his early years. When Liu Bei was prime minister of Pingyuan in his early years, he resisted thieves and was charitable at home. Ordinary people and famous families can sit with him.
An assassin went to assassinate him. Although Liu Bei knew nothing about it, he was still very polite to the assassin. The assassin was deeply moved and could not bear to kill Liu Bei. He told the whole story and then left. It can be seen from this little incident that Liu Bei is not kind. Before he died, he told his son not to do small evils, not to do small good, but to serve others with virtue. How can such a person be heartless? Besides, Liu Bei was a semi-orphan since he was a child. He lives by knitting straw sandals with his mother. When he was fifteen, his mother asked her to go out to study. Maybe Liu Bei can still disobey his mother's orders and honor her at home instead of studying. In this sense, Liu Bei can't toss and turn with his old mother when his career is not finished. Liu Bei proclaimed himself emperor at the age of sixty. At this time, his mother is long gone. Who should he mourn for?
Second, its slogan is to help the Han family and avenge my brother.
Liu Bei has been thinking about the Han Dynasty all his life, whether he is thinking about Emperor Xian or Emperor Zhaolie. Throughout his life, Cao Pi never proclaimed himself emperor until he replaced the Han Dynasty. As an ambitious man, it is understandable that he proclaimed himself emperor after Cao Pi replaced the Han Dynasty. Liu Bei's ambition does not mean disloyalty. If he continues to be loyal to Emperor Xian of Han Dynasty, it will be foolish loyalty and bad loyalty.
Let's talk about injustice. When Liu Bei heard that Guan Yu was killed, he sent his troops to crusade against Wu Dong with the slogan "Revenge"! No matter what his purpose is, Liu Bei sent troops in the name of revenge, and he can't help but be wronged!
No matter from any angle, infidelity, injustice, ruthlessness and unfilial are not applicable in the Three Kingdoms! In other words, the desire for power, in ancient times, there was no loyalty, filial piety and benevolence. Li Shimin can kill his brother and force his father to take power, while Zhao Guangyi fabricates history for the throne. From these things, what is loyalty, filial piety and benevolence? In short, Liu Bei is not a first-class hero in the novel, nor is he a disloyal, unjust and unfilial villain.
