Write a poem that tells us the truth in the poem "Topic Xilin Wall"

The poem "Topic Xilin Wall" tells us a truth: I don't know the true face of Lushan Mountain, I am only in this mountain.

I can't recognize the true face of Lushan Mountain because I am in it.

What these two sentences tell us is that people's understanding of objective things is bound to be one-sided because of their different positions and starting points; To understand the truth and the whole picture, we must go beyond the narrow scope and get rid of subjective prejudice.
