How to simply divide the southeast, northwest, southeast and northwest is it related to the yin and yang sides of the house? What does it matter? I hope to be more detailed. urgent

Direction of the sun: The sun rises in the east every day and sets in the west in the evening, which is a natural law. When people stand facing the sun, the front is west, the back is east, the left is south, and the right is north.

Generally speaking, it is best for the house to face south, that is, the house is located on the north side, the back of the house faces north, and the door opens on the south side. Sitting facing south basically means that the main functional rooms (such as living room and master bedroom) of the house are facing south, or the main lighting surface of the house is on the south side.

Extended data

On the earth, the direction pointing to the center of the earth is down, the direction facing the center of the earth is up, and the up and down are vertical. On the ground plane, east (due east), west (due west), south (due south) and north (due north) are the four basic directions.

The north-south direction is determined according to the longitude lines, and all the longitude lines indicate the direction of due south and due north. The direction along the meridian towards the north pole is due north; On the contrary, the direction along the meridian towards the south pole is due south. Because the meridian is a semi-circular line segment with a certain length, and its two ends are connected with the South Pole and the North Pole respectively, the north-south direction is limited, that is, both due south and due north have ends.

Go to the south pole (due south) along the meridian, reach the south pole, and reach the end of the south. When you reach the South Pole, if you keep going, you will no longer face due south, but face due north. In the Arctic, the opposite is true.

At the South Pole and the North Pole, latitude is no longer a line, but a point. According to the geometric concept, two special latitudes, 90 south latitude and 90 north latitude, can no longer represent things. So in the South Pole and the North Pole, it should be said that there is no east-west direction.

There are countless meridian convergence points in the north and south poles, and the direction here is only north and south: at the South Pole, all directions around are due north; At the North Pole, all directions around are due south.
