I don't know about insurance. Just go to the immigration office for a physical examination. It's quick and easy. Didn't they send you an email and a dormitory form? Dormitory can choose one room and two rooms for four or six months. The dormitory fee is paid in one lump sum. If it's six months, it's about 15000 RMB, so bring enough money. I'm not an exchange student. I have different requirements and don't know much about it. I may need public documents to prove my kinship.
