The second question is not very clear. Go in from the east gate of Zheng Da, and take the right road to the west, about 300 meters. The library is on the right of the road.

If you enter from the north gate, go straight south, turn left at the first crossing of Jinshui River, and go straight for about 200 meters, you will see the library on the north side of the road.

If you enter from the south gate, go straight north, turn right at the first crossing, and the library is about 200 meters north on the same road.
