These two stars are very fortunate in period 7. This door should be used often. However, if we don't do anything to activate or enhance a good star it cannot bring us the luck we want. Good stars are to be supported with proper forms to bring out their usefulness. The prominent mountain star 7 has to be supported by a mountain.
Mountain can be real mountains or virtual mountains such as houses and buildings.
You can also put an aquarium on the left side of the door from inside looking out. If this happens to be the west area, it is not recommended to put water in west area in period 7. The bad combination 2-3 at the center palace has to be cured. Star 3 is wood. To cure its bad influence, fire is needed to weaken wood like red lamp.
