The poem "Xilin Wall in Titing Pavilion" says: "Looking horizontally, the ridge side becomes a peak, and the distance is different. I don't know the true face of Lushan Mountain, but toward which corner of the mountain. "

Meaning: I can't recognize the original face of Lushan Mountain because I am in it.

Appreciation: "I don't know the true face of Lushan Mountain, but toward which corner of the mountain", this is the experience of reasoning on the spot and talking about traveling in the mountains. Why can't you identify the true face of Lushan Mountain? Because I am in the middle of Lushan Mountain, my vision is limited by the peaks of Lushan Mountain, and I only see one peak, one ridge, one hill and one valley of Lushan Mountain, which is one-sided and inevitably one-sided. This is what you see when you visit the mountains, and it is often the same when you observe things in the world. These two poems are rich in connotation and enlighten people to understand a philosophy of being human-because people are in different positions and have different starting points, their understanding of objective things is inevitably one-sided; To understand the truth and the whole picture, we must go beyond the narrow scope and get rid of subjective prejudice.
