Is it higher in the Feng Shui room than outside?

All right! It should be higher inside than outside. The front steps of building houses in rural areas are very important, generally the highest nine steps. The house is flush with the highest steps, and there are thresholds inside and outside the house. Office buildings in cities generally have many steps, the first floor and the highest floor. There are five reasons why the indoor ground is higher than the outdoor ground: first, to prevent foreign gas from entering the house; Second, step by step; Third, pass on wealth; Fourth, moisture-proof in summer; Fifth, get angry.
