A few years of college life has become the best memory of life. There used to be songs and laughter, as well as melancholy and sadness. Skipping classes, playing games in Internet cafes, drinking with a few like-minded students, or writing vows in the snow for a beloved girl in the frozen winter, people can't help but miss those scenes all the time.

I believe that every student has the happiest or saddest moment in his college years. Looking back now, it seems that just yesterday, the most frustrating thing for me was when I was in the subject exam, so I was sure that I failed, and I couldn't figure it out. I usually study very well. Because of this, I hate the old man who has taught this course for two years. Now that I think about it, I can't bear to look back!
