One day during the Spring Festival, an old classmate asked me out. While we were chatting and laughing, she suddenly wanted me to write about her. My writing skills are mediocre and I can't write anything good. Her life is monotonous and it's not a good subject, so this matter has been postponed again and again, and it's here now. Now, I am 25, and she is 24, and we are both running wildly on the road to three without looking back. When I got off work these days, I looked at the setting sun outside the window and the newly blooming peach blossoms, and suddenly I felt that no matter how monotonous life is, if you look closely, there must be joy and sorrow. Every time of everyone is worth recording. Although many memories have been blurred, I decided to try my best to write about her, and at the same time look back on my own youthful years. So this article is about my classmates, my classmates' classmates and friends, and the story of Meng Changhe. May our youth never wither.
