Returning to the old high school classroom again, the tables and chairs that have not been replaced still bear traces of our past. Colored candles from youthful years, the candlelight swaying and bright. The senior year of high school is unforgettable, and the senior year of high school is even more unforgettable. It is the supplement to the senior year of high school. The senior year of high school is like a beautiful, aqua blue night sky, shining with brilliant stars. Now, while savoring it carefully, I want to use the pen in my hand to describe the most brilliant stars, and use the pen in my hand to write the footprints of youth left on campus.
