Spring, summer, autumn and winter, also known as the "four seasons", are the results of the earth's orbit around the sun. Spring begins with "beginning of spring" in the 24 solar terms, and summer begins with "Long Summer". Autumn begins with beginning of autumn; Winter begins in beginning of winter.

While the earth revolves around the sun, it also rotates around its own axis, but the axis is not perpendicular to the orbital plane, but has an inclination of 23 degrees and 27 minutes, which makes the direct point of the sun on the earth's surface move between the Tropic of Cancer and the Tropic of Capricorn, thus forming the four seasons.

When the sun shines directly on the Tropic of Cancer, the northern hemisphere gets more solar heat, and the day is longer than the night, so the highest temperature in the northern hemisphere is summer.

At this time, the sun shines obliquely in the southern hemisphere, getting less solar heat, and the night is longer than the day. Therefore, the southern hemisphere is in the coldest season of the year-winter.
