There should be food, and it will be sold near the university. As for where to live, there may be arrangements. If you go too early, you can consult the management of the dormitory over there. If it's really bad, don't go so early. The university is very good. Don't worry about anything. You don't have to go so early. You can prepare what you want to bring at home now, and it's not too late to wait until the school starts soon!
