Many ancient scholars had a desire to go into politics. What is the reason?

At that time, I didn't want to study what scholars can do now, so I could only find my way through that pile of old paper.

Not everyone wants to go into politics. Isn't it rare for military commanders to go into politics?

Second, they want to repay the wise Lord. More officially, they want to be famous and go down in history.

It's that simple. Of course, there are 1L words, in order to keep yourself alive!
