I don't know if you have applied for a dormitory. If you apply for one of the thirteen pavilions of HKU, the accommodation environment will be very good. There is a mattress in the shed, so it is enough to prepare sheets and pillows at ordinary times; There are wardrobes, desks and bookshelves. For specific styles, you can go to different websites to see pictures. Generally, there is a pantry on each floor of the hall, where you can cook (kitchen utensils are generally available, but tableware must be brought by yourself), as well as public toilets, which are cleaned by specialized personnel.
It doesn't usually take long to communicate, does it? You don't need to bring too many things, just basic documents, clothes and the like. Most daily necessities can be bought in Hong Kong when it is inconvenient to take them with you. You can buy it in many places in the West Ring Road, which is very cheap.
