What feng shui problems should I pay attention to when renting a house?

Whether the vertical direction of the house is reasonable or not can be identified in an intuitive way by looking at the back hill and the front hall. Especially for houses with water on the back of the mountain, if the longitudinal axis of the building is obviously deviated from the top of the back mountain and the front hall is obviously biased to one side, then the orientation of the house is definitely unreasonable. To accurately determine whether the vertical direction of the house is reasonable, it is necessary to use a compass to determine the vein, determine the spout and measure the sitting direction, so as to truly determine. This requires a systematic study of the basic principles of Feng Shui and the use of compasses.
