Is the house on the overhead floor feng shui good?

It depends on the time and place. There is no winter in the south, so the raised floor is necessary to keep it ventilated and dry, but not in the north, which affects heating. In hot and humid places, the ground floor is not well built, and snakes, rats, insects and ants and returning to Nantian will particularly affect the experience. Even many villas are built on the first floor as garages. In addition, if the overhead floor is above the gatehouse, don't buy the car below, which is noisy.
