My name is Zhang Yu, I am a freshman, and today is my first day at school.Because I contacted the senior sister of the student union in advance, I am now standing at the school gate waiting for my senior sister to pick me up to the dormitory.My senior sister’s name is Zhao Huanhuan. During the summer vacation, I joined the college’s WeChat group. Not long after I introduced myself in the group, my senior sister Zhao Huanhuan joined me. As soon as I passed, my senior sister sent me a message first. Hello, brother!
