How to determine the orientation of buildings towards geomantic omen?

The sitting direction of the house comes from the front and back position when people sit. When people sit, the position of the spine is sitting, and the position of the front of the body is facing. That is to say, face to face and sit on the back. The "sitting" of the house is the position of the rear end of the central axis of the longitudinal building on the ground plane, and the direction is the position of the front end of the central axis. In geomantic omen, twenty-four mountains are used to represent the sitting orientation of a house. The sitting direction of the house is determined by the longitudinal axis of the building. Generally speaking, the vertical line of the back wall of a house is sitting, and the other end of this vertical line is sitting. Sitting orientation includes sitting orientation of the house and sitting orientation of the door. The door and the house sit in the same direction, but there are also differences. For doors with different orientations from the house, additional measurements should be taken. First, the sitting direction of the whole house: in principle, the longitudinal axis of the house is the sitting direction of the house. Second, the sitting direction of the door: 1, the gatehouse: a house with a yard. The main gate of the courtyard was called the gatehouse in ancient times, because the ancient gates were tiled and were an independent unit of the building complex. Now it can be called courtyard gate or garden gate. The sitting direction of the main entrance is the same as that of the main building, and some are different from that of the house. Therefore, the door-oriented method is inaccurate. The main entrance is the main air inlet of the general courtyard, and the position and sitting direction of the door in the courtyard have an important influence on the geomantic omen of all houses in the courtyard. The ancients said, "There are four halls in the gatehouse", which means that the general gate is very important. Whether the location of the general gate is reasonable or not, and whether the sitting direction is correct or not, determines the feng shui quality of the general courtyard. Yang Gong's geomantic omen emphasizes that the gatehouse must be set in a prosperous position with accurate orientation, so as to accommodate the vitality of the hall outside. What is the position of prosperity will be explained in future lectures. 2. Unit master door: A high-rise building in a city divides a building into several units, and the master door of each unit is the unit master door. In general, the sitting direction of the unit main door is consistent with that of the building. The feng shui pattern of the main entrance of the unit has an influence on all the units entering and leaving this door. 3. Unit door: that is, the main entrance of each independent unit room. The sitting direction of the unit door is the same as that of the whole building, but there are some differences. 4. Room door: that is, the door of the kitchen, bedroom, bathroom and study of the unit room. Generally, the room door is located in the geometric center of the room regardless of the sitting direction. Measure the middle position of each functional area respectively to find out the position of each functional area in the unit. 5. Balcony door: the door leading to the balcony. To analyze the feng shui quality of a flat, it is necessary to measure the doors of each floor related to this unit separately. Thirdly, the sitting orientation of polygonal houses is not uniform, so it is necessary to measure the sitting orientation separately in units. How to measure the sitting direction of a house? The meaning of the sitting direction of the house is clarified, and the next question is how to measure the sitting direction. The main tool for measuring sitting posture is Feng Shui compass. In China, people pay the most attention to the orientation when buying a house. A good orientation can make the house warm in winter and cool in summer. In the south, sitting facing south is the best orientation, so Cantonese people especially like houses facing south. The living room is the place with the highest household utilization rate, and the living room facing south is better. Even in winter, you won't feel the cold wind, and summer is refreshing and pleasant. If the balcony and indoor windows are designed as convection to form a "direct flow", then you can enjoy the cool breeze at home. The bedroom is a place to rest, and people sleep about 1/3 every day, so it is very important to choose a good bedroom. Consumers should take the orientation of the master bedroom or most bedrooms as the standard. The bedroom facing south is also better, but it is best not to rely on the outer wall. Because in summer, the bedroom facing south is cooler, but there is more sunshine than the room facing north. If the outer wall faces south, the indoor temperature will definitely be higher. Bedroom orientation can be southeast, east and northeast, and it is best not to choose a bedroom facing west. There aren't many bedrooms facing north, so one is enough, because the bedroom facing north is cold in winter and cool in summer. The orientation of the living room and bedroom should be suitable for receiving direct light, preferably facing south or south. Generally speaking, sunlight can penetrate for 2-3 hours a day, which is beneficial to eliminate indoor moisture, kill bacteria, adjust indoor temperature and accelerate air flow. The orientation of the kitchen and bathroom is relatively small. As long as the bathroom can be directly lit and ventilated. Because its use is intermittent and short-term, it is best to avoid choosing a bathroom facing west. For the kitchen, avoid facing west, because the kitchen already has a heat source, and the temperature will be higher if it receives direct sunlight. The bathroom should also be able to receive some sunlight. Because the bathroom is dark and humid, sunshine can avoid the breeding of germs. A house is a lifetime thing. Choosing a room with a good orientation can let residents live here and really enjoy the natural life. This answer was recommended by Zhang Xue, an expert in the classification of science education.
