HKUST's address is Wei Long Road, Taipa, Macau, so you should write the address: Wei Long Road, Taipa, Macau, followed by Macau University of Science and Technology, with her dormitory number and recipient's name. It will be sent to the student affairs office, and you can inform the recipient to pick it up.
I asked the student affairs office before, but the man didn't make it clear for a long time, and I didn't try to send it specifically. If it's important, don't send it casually. ..
