If you don't plan to live on campus, Dong Jiu can go off campus when he comes out. There seems to be an exchange center or something, but I haven't lived there. I am from the main campus.
If there is a guest house (off-campus) outside the Optics Valley Gymnasium in the east of the main campus, it seems that the students stayed when they came to see me together, and it will take about 15 minutes to leave the east for a long time. Dongjiu seems to have a place to live, but it seems a little expensive. You can come and see it one day in advance. There are quite a few guest houses nearby. If not, you can live near Sekinoyamaguchi (the main entrance of Huake) and take the school bus to Dongjiu in the morning (direct flight).
