Where does the sun rise and set in summer and winter?

I don't agree with the story upstairs.

During the summer solstice, the sun rises at about 25 degrees northeast and sets at about 25 degrees northwest.

During the winter solstice, in the latitudes of China, the sun rises at about 25 degrees southeast and sets at 25 degrees southwest. In summer solstice and winter solstice, the azimuth difference of sunset can reach 50 degrees.

The equatorial region is the smallest, at 47 degrees. The higher the latitude, the greater the difference. In northern Russia, the sun almost always rises from the north in summer (within 30 degrees east of the north, the higher the latitude, the smaller it is), and the temperature difference can reach more than 100 degrees, and it can reach 180 degrees in the Arctic Circle.

So, I don't agree with the upstairs, there is still a big gap.
