The southeast door of the rural gate opens, but the front of the door is empty and faces the crop fields. Is anything wrong?——Congratulations! If the front door is open and flat, it is a place where gold and silver treasures are piled. "With a big dragon and a big cave, the front door must be able to accommodate thousands of troops and horses." This is a wise saying in Feng Shui books. Crop fields have always been viewed as granaries in Feng Shui, and a large area of ??crop fields is a large granary. In front of the door is an open field with crops, a land of treasures and a granary.
