My classmate Tang Xiaocheng and I were roommates in the nursery, kindergarten alumni, deskmates in elementary school, junior high school classmates, and high school students. She didn't go to the art class until she was separated into arts and sciences classes in her second year of high school. Until now, we have never seen each other for more than a week. I don't know that Chen Yi's sister worked overtime at work and I went to Tangjiapu to eat because her parents lurked her in my house. We would have a fight within half an hour of each other.
