From millenium hotel, what should i ride to go to xiamen huaqiao university? thanks

Do you refer to Millennium Harbourview Hotel?
If yes, take public bus no.950, get off at Duishan Station. Then walk southwest around 560 yards (510 meters) to find the campus.
Or from the hotel, just get a cab directly. The cab fare is CNY 60 to 70 in the day time.
