Xunzi used two poems to describe the importance of learning to climb high and look far.

I've tasted it and I'm looking forward to it. Let's go hiking. Climb a trick, the arm does not lengthen, but the person you see is far away;

I once stood on tiptoe and looked at it from a distance, but I didn't see it as wide as when I was climbing. Climb high and wave, the arm is not longer than before, but others can see it in the distance; People's own qualifications are limited, and they need to acquire knowledge through learning to improve themselves.
