What are the taboos for feng shui in porch decoration?

The porch also has some taboos in geomantic omen, for example, the interval between walls should not be concave and convex, and the ceiling should not be low. The first taboo of porch feng shui: the wall interval should not be uneven. The porch wall should not be uneven. In order to decorate more creatively and beautifully, some people will use stones to decorate the porch, thus creating a concave and convex wall, which is very bad. Because the porch is the entrance to the gate, if it is uneven, there will be many obstacles in the house transportation, which must be avoided as far as possible. The porch feng shui taboo 2: the ceiling should not be low. The porch ceiling can be high and not low. Too low a ceiling will produce a strong sense of oppression. From the perspective of Feng Shui, this is an ominous sign, which symbolizes that family members are oppressed and constrained, and it is difficult to get ahead. The ceiling is high, the air circulation in the porch is more comfortable, which is also of great benefit to the gas transportation of the house.
