What is the latitude of direct sunlight at vernal equinox, summer solstice, autumn equinox and winter solstice?

At the vernal equinox, the sun shines directly at the equator; From summer to the sun, the sun shines directly on the Tropic of Cancer (23 degrees and 26 minutes north latitude); At the autumnal equinox, the sun shines directly at the equator; On the solstice of winter, the sun shines directly on the tropic of Capricorn (23 degrees 26 minutes south latitude).

Not only the climate in different parts of the earth is very different, but also the climate in different seasons in the same area is different. There are four seasons in a year, spring, summer, autumn and winter, and each season lasts about three months.

The bottom "three" means (the first month when the sun enters winter). The sun can shine into the room and draw on the ground. The middle "three" means (the second month when the sun enters winter) and "eight" means "winter".

There is an included angle (23 26') between the earth's rotation axis and the earth's revolution plane around the sun (ecliptic plane). Therefore, when the earth revolves around the sun, the position of the direct sunlight on the earth will change from 23 26' south latitude to 23 26' north latitude, that is, the tropic of cancer.
