1) Open the Rosefinch Gate
In front of the house is a place where lakes, seas, rivers, ditches, rivers, ponds, marshes and water or steam gather. In this case, the middle door should be opened. If the front of the house is flat and not inclined, it is not a hillside, and there are no ups and downs in the vicinity. In this case, it is also appropriate to open the middle door.
(2) Open the Qinglong Gate
Feng Shui takes Tao as water and pays attention to context. Geogas flows from high places to low places. If the water flows from the tiger side to the dragon side, that is, the right side of the terrain is higher than the left side (standing at home and looking out), the water flow or airflow flows from right to left, or there is a street or corridor in front of the gate, where the right side is long for incoming water and the left side is short for dehydration, it is appropriate to open the left door to draw and collect the geogas. This method is called "Qinglongmen Gas Gathering".
(3) Open the White Tiger Gate
Water flows from the dragon side to the tiger side, that is, the left side of the terrain is higher than the right side, and rivers, roads, water flows and air flows from left to right. Such a house is suitable for opening Humen. There is a street or corridor in front of the door. The left road is long for incoming water and the right road is short for dehydration. Therefore, it is advisable to open the right door of the house to extract air and collect gas, which is called "White Tiger Gate Gas Collection".
