"Swallows are thick, bamboos are thick, smoke is thick, and rivers are always easy-going." In the peaceful and simple campus life, everything is uneventful, but the peaceful life will eventually be intruded by people who break the tranquility. And his intrusion made the originally peaceful life sparkle. Is the person who accompanied you from school uniform to wedding dress still around? So you must cherish the people who are by your side now.
Intention: Don't wait until you lose it before you know how to cherish it
