I have a layover at Guangzhou Airport for 7.5 hours (from 1:45pm to 9:20pm), I would like to go sightseeing during this time. The Huangpu Academy would be my favorite place to visit. Would it be realistic to make it to the Academy before it closes (seems to be at 5:00pm) and back? How would I go about it? Take the bus to the Sanyuanli metro station? Then take the metro to the "university city north station" and finally a taxi to the academy? Is that realistic? Thank you, Bob.
