What if the foundation of the main house is lower than the road outside the yard?

In principle, the floor inside the house must be higher than the aisle outside. It is easy to cause the water running in the corridor to stay in the house and the water running in the house can't get out. From the perspective of geomantic omen, remedial measures:

1, raise the height of the threshold, and the threshold is to block money.

2. Spread wooden floor or composite floor on the basis of the original indoor floor to increase the original floor height.

3. If the wooden floor is not practical, add a thicker foot pad at the indoor entrance, just beyond the outside.
