When the sun shines directly on the Tropic of Cancer, which solar term is China in?

Involving knowledge points:

A, the earth revolution:

The earth revolves around the sun from west to east as a revolution with a period of 365.25 days.

Second, the angle of intersection of Huang Chijiao:

The earth's orbit around the sun is called the ecliptic, and the earth rotates and revolves at the same time. The angle between the ecliptic and the equator is always 23 26', and the existence of the ecliptic angle determines the changes of the four seasons of the earth.

Third, the Tropic of Cancer:

Two latitude and longitude circles on the earth at 23 26' north latitude. 23 26' north latitude is called the Tropic of Cancer, which is the northernmost boundary of direct sunlight on the earth. 23 26' south latitude is called tropic of Capricorn, which is the southernmost boundary of direct sunlight on the earth. The Tropic of Cancer is the dividing line where the sun moves back and forth directly on the earth every year. The Tropic of Cancer is the dividing line between the tropics and the north and south temperate zones. The area between the Tropic of Cancer and the Tropic of Capricorn is tropical, where the sun shines directly all year round and the heat is the most. The area between the Tropic of Cancer and the Arctic Circle (north latitude) is the north temperate zone, and the area between the Tropic of Cancer and the Antarctic Circle (66 34' south latitude) is the south temperate zone. In temperate regions, the sun shines obliquely all year round, and the heat obtained is moderate. Most of our country is located in the north temperate zone, which belongs to the temperate climate.

Four, the characteristics of the earth's revolution:

1. The revolution of the earth is centered on the sun and rotates from west to east;

2. The included angle between the Earth's orbit and the equator is 23 26';

3. The revolution time of the earth is 365.25 days;

The revolution of the earth has produced four seasons changes in the northern and southern hemispheres.
