We struggled through the thorns along the way, comforted each other when hurting each other, wasted our time in the cruel life, rose up in the turbulent undercurrent, grew old in the bright era, looked back at our youth on the bright future, and said goodbye with tears in our hearts. That was the innocence of college days, and now I feel ridiculous and precious when I think about it. It was the government and power in the workplace, and now I feel ridiculous and disgusting when I think about it. The world is rolling in the world, and the years are gone.
