What about the four directions? Don't answer any questions you can't tell.

Gosh, you don't know this either. Azimuth, east, west, north and south, based on different reference objects, is artificially formulated. Common ones are: east, west, north and south based on the house of birth; East, west, north and south with the house you live in as the reference. East, west, north and south, according to the place of birth; East, west, north and south, divided by people's residence; With the Central Plains of China as the reference, it is divided into east, west, north and south. But no matter what kind of reference is used to divide the east, west, north and south, it is artificial and can only play a role in people's understanding of the direction.

When a person stands in a place and takes the place where he stands as a reference, he has a definite position, which is his east; Which side is his west; Which side is his south; Which side is his north? If he takes a few steps to the south where he used to stand, the place where he was a few steps away from the south will become his present north because of his physical movements. Any universal principle will change the original conclusion because of the change of reference, and it is no longer a universal principle.

The house takes its own orientation as a reference and has its own east, west, north and south orientation. However, the basic material that determines the law of human destiny, solar radiation [also called sunlight], can you know the east, west, north and south of a house, can you identify the east, west, north and south of a house in Qian Qian, and can you identify it separately?
