Why do ancient poets in China like to use natural scenery as their image objects?

First, the ancient geographical location of China belongs to monsoon climate, with four distinct seasons, so it is easy for the author to find and feel the changes of natural scenery; Second, in ancient China, traffic can reach its destination without sleeping on modern high-speed rail, while in ancient China, the world was completely measured by feet and would not be scattered all the way; Third, ancient literati were always on the road, such as going to Beijing to take exams, being demoted or promoted. You can understand Su Shi's relegation at that time.
