I have lived in the South District since my sophomore year. There are four people (beds above and desks below), and some buildings provide two people (not bunk beds), which is relatively small. Physics, mathematics, Chinese, history, mechanics, philosophy and so on will all be in the southern district.
If I study medicine, I will move to LAM Raymond campus in my sophomore year. I don't know the accommodation there. I haven't been there.
The size of the bed is 2m *1m.
