Long Zhen, the point is true. Hidden feng shui, mountains and rivers are affectionate, and mountains and rivers are used by me. The mountain dragon and the water dragon must meet, so that the hall is just right and the cave is just right. The direction of dragon water must be matched, so as to combine the talents of heaven and earth. Only through these comprehensive considerations can we find the real treasure house of Feng Shui. Solemnly declare: the answer is for reference only, please don't be blindly superstitious.
