I have met many people during my four years at Jiangsu University, including roommates, friends, people I loved and people I hated. College is just a short moment in life, but sometimes I think it is a lifetime. Because in the past four years, I have experienced touching, happiness, the happiness of being loved, the pain of not being loved, the reluctance of not being able to love, and the regret of missing each other when we could have fallen in love. Because it was so profound, even after many years, everything that happened back then is still vivid in my mind. We cherished each other enough when we met, but it still didn't stop us from being heartbroken when we were separated. My classmates, after so many years, how are you?
