Do you know which direction the sun comes out of?

It is often said that "the sun rises in the east and sets in the west", and it is customary to use a point on the horizon of the sunrise to represent the East, and a point of the sun-setting horizon to represent the West. In people's minds, the sun's haunting point is a sign to judge the east-west direction of the ground. Strictly speaking, however, it is obviously incorrect to judge only the location of the sun as the positive east-west direction of the ground level. Because, due to the rotation and rotational motion of the Earth, as well as the existence of the Yellow-Red Angle, on the surface of the Earth, in different seasons of the same latitude place, or at different latitude sites of the same season, the place where the sun rises east on the horizon and sets in the west will change significantly, and it is impossible to always be at a fixed due east and west point everywhere. So, where exactly is the sun relative to the horizon? How does the location of the sun change in a year?

It was concluded that the geopolitical position of the solar infestation site, whether it was the southern or northern hemisphere , regardless of whether the observation site was located in the northern and southern hemispheres , depended on whether the sun was directly hitting the southern or northern hemisphere , regardless of the location of the observation site in the northern and southern hemispheres.

Specifically:

1. Theoretically, at the two-o'clock sun, the sun shines directly at the equator, and the sun rises in the east and sets in the west (except for the poles);

2. In the summer half of the northern hemisphere, the direct sun is in the northern hemisphere, and the sun rises in the northeast and sets in the northwest around the world, and the higher the latitude, the more north the direction of the sun rising and setting, and the same is true in the northern and southern hemispheres (except for poles and places where extreme day and night appear);

3. In the winter half of the northern hemisphere, the sun directly hits the southern hemisphere, and the sun rises southeast and sets in the southwest around the world, and the higher the latitude, the more south the direction of the sun rising and setting (except for poles and places where poles and nights appear).

4. For a certain place, during the northward movement of the direct point of the sun, the direction of the sun's rise and fall will become more and more northward; otherwise, it will become more and more southward.

5, on the north and south poles, the sun height is unchanged throughout the day (that is, the sun's Sunday visual trajectory is always parallel to the horizon of the pole), and the sun does not rise and fall significantly throughout the day.
