As for the principle of distribution, students in the same class live in the same dormitory. When I was a freshman, I usually chose it myself. If your friends are in the same class as you, they can be together, but sometimes they will be divided according to their student numbers, but in fact, their student numbers are the rankings of their grades.
Day study means that students who live close to home can go home at noon and after 5: 20 pm, and they can choose to finish their evening study at home or at school, and finish their evening study at 10: 00.
