Is there a kitchen behind the altar? why

Not good! The stove should not be opposite to the altar, but will collide with it, because it is not suitable for offering sacrifices to gods in filthy places, because the dirty air in the kitchen and the dirty air are easy to fall above the altar, which will inevitably bring bad luck to the family. Moreover, both the stove and the altar belong to "fire", and fire is opposite. The wall behind the altar should be a solid wall, not a gypsum board or a lightweight wall. Altars are not suitable for bedrooms, toilets and toilet doors, kitchen doors and damp places! The altar is not suitable to be placed under clothes, especially underwear! It is forbidden to make a door punch on the altar. It is very important to rush the door to affect the peace of the gods. If the gate is too close to the altar, especially some new buildings, once you enter the gate, it is only a few feet away, and then you enter the living room through a narrow horizontal corridor. This design is not conducive to placing the altar in front of the gate, otherwise the force of rushing the gate will be very great, which will affect the quiet atmosphere of the gods and cause damage to Feng Shui.
