Feng shui is to look at the whole. Choosing a house is to see whether the building is in a prosperous position according to the surrounding environment and the mountain trend of the community, and then measure the floor direction of the building and take the floor that is coordinated with the direction of the building. When determining the floor, it is necessary to measure the mountain direction of the house to see if the mountain direction is prosperous and can match the surrounding scenery. Whether the indoor layout is reasonable, such as whether the prosperous position is open, whether the important positions such as the big meal, kitchen and master bedroom are in the prosperous position, whether there is no place washed by the external environment, and so on.
