If you say: You are now standing in "Shanghai Book City".
You walk along one side of "Shanghai Book City" (that is, along the direction of traffic flow) towards "People's Square".
Cross two blocks and stop where you haven't crossed the third road.
You will see the building of Huangpu District Library.
Below the signboard of Huangpu District Library is the Shanghai Music Bookstore ~~
It contains first-hand imported discs.
