I am a student of Ningda University. Hehe, Baoyu Bookstore is the library of our school. In the old campus of No.818 Fenghua Road, Ningbo, you can see the Baoyu Bookstore along the central axis of the school when you enter the gate. There are signs of "reading room" and "intelligent building" on it.
As for how to get to Ningbo University, if you live in Ningbo, you can take 54 1 546 to Ningbo University in the city. If you don't live in Ningbo, take the bus to the South Station first, and then take these two buses directly to Ningda.
Let me give you a picture. Here it is.
