This article records the campus life of the university from the perspective of a boy in a relaxed and slightly exaggerated way. You can understand it as a nostalgia for that period of time, a trajectory of mood, whether it is joy, pain, sweetness or sadness, it is not a blank after passing through. Time is passing by quietly, and the years have no cantabile. Perhaps at the moment of looking back, you will find that the original thrilling scenery has long been gone, and all that is left are memories, deep or shallow.
