Each of us has a bright or dull growth path, leaving a series of deep and shallow footprints. Like the scenery a train passes by, even a moment is enough to leave a mark on the bottom of my heart, making me feel lost at the corner. These scattered words are a young man's nostalgia for the good times of his childhood, his thoughts and reflections on the various experiences he has experienced now, and they are a lasting note for Caiyun Zhuiyue in the future. Each word may not be gorgeous, but the author writes it with care, leaving traces of growth.
