Which floor is the best on the eighteenth floor?

I am a real estate planner. Let me talk about my opinion: 1 and 1-5 floors: the view is the worst, and the cars coming and going downstairs are noisy and there is no outdoor landscape. Floor drains stink easily, and the floor 1-2 can still be wet, especially in the first two years. (From the perspective of geomantic omen, people should be grounded, so 1 building is the best. Rural people value this more. They are willing to live on the 1 floor and think that grounding gas is not good for their health. 2, 6-9 floors: general view, outdoor view but 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. 6. 17- 18 floor: 17 floor can be considered, because the elevator machines are placed on the roof, and the noise of the elevator on the top floor is very loud, which is still obvious at night, so 18 floor need not be considered. If the elevator is a good brand, it is also good. Don't consider the building of 18, it is hot in summer, and it will leak if it is not waterproof. 7. Choose a house with transparent north and south, which is well ventilated and cool in summer; Pure south is hot for houses, and the air circulation is poor; Secondly, choose the house in the east, then the house in the west, and the house in the west is basked in. If the kitchen is in the west, the food will go bad easily. Don't buy the northwest wind howling in winter! Although it is more expensive to live in a good building, you have to live for a lifetime, or your children and grandchildren will live in the future. Why do you wronged yourself, spread it equally for 70 years, and have no money every year?
