Su Shi, a poet in the Song Dynasty, wrote a poem entitled Xilin Wall, which contains the following philosophical principles.

The last two sentences are the author's deep thoughts: the reason why we look at Lushan Mountain from different directions will have different impressions because we are "on this mountain". In other words, only by staying away from Lushan Mountain and jumping out of its shadow can we fully grasp the true face of Lushan Mountain. The whole poem tightly hugs you Shan to talk about your unique feelings, and expresses philosophy in a simple way with the help of the image of Lushan Mountain, so it is kind and natural and intriguing.
