All three of them are my graduate roommates. First left is a quiet girl from the Northeast. She came to Chongqing to study over 1000 kilometers. As the farthest away from home, she is the group pet of the dormitory. The roommate leaning on the backpack in the middle is a native of Chongqing. She is the youngest sister in our dormitory. She is very free and easy and has a childlike temperament. The roommate on the far right is from Sichuan. She is our big sister. As a big sister with two sisters at home, she automatically takes the role of sister in our dormitory. She is very caring and reliable. And as a recorder, I am a chatterbox in the dormitory. This warm, harmonious, joyful and moving photo is our precious memory, and it is touching every time we look back.
