What is the relationship between Liu Bei and Emperor Xian of Han Dynasty?

At first, it was really good. At that time, Liu Bei was famous for his benevolence and righteousness. Emperor Xian of Han was once again bound by Cao Cao, and he was very sad. Finally, one day, he came. Ignorant Dixian really took him as an uncle. It's sad to cry with Liu Bei in your arms. Immediately gave him a reputation, so this Liu Huangshu is very reasonable. In order to get rid of the shackles of Cao Cao, Emperor Xian of Han Dynasty also wrote a bloody book, in which Liu Bei participated. In order to avoid hurting Emperor Xian of Han Dynasty, Liu Bei motioned Guan Yu not to act rashly, which also saved Cao Cao's life.

Later, after Liu Bei established his hegemony, he felt that he didn't care much about Xian Di. I run a small country myself, and occasionally I sigh that Cao Cao holds the emperor to make the princes. Actually, I'm a little overwhelmed. Even if I want to find him, I'm at a loss. In addition, I personally think that it has actually reached this point. It can be said that Liu Bei no longer cares about the life or death of Emperor Xian of Han Dynasty, but only cares about himself.
