"Looking back to the desolate place, when I return, there is no wind or rain or sunshine." This finishing touch, full of philosophical meaning of life, expresses the poet's epiphany and understanding gained in the subtle moment of nature. Enlightenment: Since the rain and sunshine in nature are ordinary and no different, the political situation, honor and disgrace in social life are of no concern? The word "desolate" in the sentence means the sound of wind and rain, which corresponds to the "sound of beating leaves through the forest" in the previous film. The word "wind and rain" is a pun, which not only refers to the wind and rain encountered on the way to the wilderness, but also alludes to the political "wind and rain" and the dangerous journey of life that almost killed him.
