2, 6-9 floors: the view is general, and you can see the outdoor landscape, but it is not the best viewing height.
3. Layer 10- 12: floating layer, preferably not selected.
4. 13- 14 floor: Generally, the machine for the second water pressure increase is easy to be located in the middle floor, and the house with 18 floor may be located in the 9- 14 floor. Before buying, you should ask clearly. Generally, salesmen are not sure which floor this is on. Shallow people may not know it at all, so it's best to look at these two pictures on the spot.
5. Floor 15- 16: I think this is the best floor, with a good view and lucky numbers over the floating building.
