I want to travel to Hong Kong. I want to visit the University of Hong Kong.

I suggest you go to Hong Kong Polytechnic University. When I visited Hong Kong, I went to this university. The traffic is very convenient! At Luohu Port, take east rail line to Hung Hom Station, then go north, take Exit A and cross the overpass to the Hong Kong Polytechnic University. There are travel notes of Hong Kong in my space. You can go and have a look. I hope it helps you. You can ask me if you don't understand.
