Ancient literati often send their feelings to mountains and rivers. What is the reason?

No one knows his ambition and thoughts, and the mountains and rivers are magnificent. I feel that the mountains and rivers in nature are all-encompassing, so I unconsciously use mountains and rivers to express my lofty aspirations and broad mind.

In other words, there are some talented people with certain family background, but they have no ambition to display their talents. They no longer have much hope for worldly things and disdain to associate with a group of utilitarian people. Then live in seclusion in the mountains and rivers and live a carefree life.
