At the end of the summer of 2017, as a bell rang, the college entrance examination ended. Our youth also goes with it. Three months later, with either unwillingness or satisfaction, we stepped onto campus and met new friends, who either got along or didn't get along. In such an environment, we started a new journey, met new friends, and had a life different from any previous moment. In the past four years, we have laughed and cried together, and we have regained our confidence through experiences of injustice and injustice and random acts of kindness by strangers. Whether it is to study hard or hide in a place no one knows about on the weekend, order a cup of tea, read a book, and enjoy a few hours of leisure time from the busy work. This is another period of youth. Get on the time bus, look at the scenery one after another outside the window, hold a cup of fragrant tea, and share your past time with the people around you. It's another time.
