In winter, eggs are about to hatch. This solar term means that the spring is getting stronger and the temperature is rising, but when it is warm, the temperature and wind force change greatly.

4. Equinox: On March 2 1-22, the sun moves to 0 degrees and the sun shines directly at the equator. "Minute" means "half" and is the midpoint of 90 days in spring, which is called vernal equinox. This day is equal to day and night, and the overwintering crops in vast areas of China have entered the spring growth stage.

5. Tomb-Sweeping Day: On April 5-6, the sun moved to 15 degrees. This solar term means that the temperature is getting warmer, plants are sprouting, and beautiful scenes appear in nature.

6. Grain Rain: From April 19 to April 2 1 day, the sun moved to the longitude of the Yellow River at 30 degrees. "Rain has bred hundreds of valleys." From that day on, the rainfall increased, which was beneficial to grain growth.

7. Long summer: On May 5-6, this solar term means that everything grows in long summer, hot weather comes, and farming activities enter the busy season in summer.

In the north, it is the time to cut wheat and plant rice, and it is also the busy season of agriculture. Summer harvest, summer management and timely visit to summer broadcasting are necessary.

10, summer solstice: June 20-22, when the sun moves to 90 degrees of the yellow longitude. The sun shines directly on the tropic of cancer, so it is called "summer solstice". On this day, the northern hemisphere has the longest day and the shortest night, which indicates that summer is coming and the temperature will continue to rise.

From summer to around, many places in China enter sultry summer, and the temperature is generally above 30 degrees Celsius, and the highest temperature often exceeds 37 degrees Celsius.

1 1, slight summer heat: On July 6-8, the sun reached 105 degrees and entered summer, marking the high temperature season in most parts of China.

12, summer heat: July 22-24, when the sun reaches 120 degrees, just before and after the midriff. This period is the hottest period in most parts of China in a year, but there are also abnormal years of "not hot in summer" with more rain.

13, beginning of autumn: August 7-9, when the sun moves to 135 degrees. This solar term means that the hot summer will pass, the crisp autumn begins, the vegetation begins to bear fruit, and it is the harvest season.

15, Millennium: September 7-9, when the sun reaches 165 degrees. As the direct point of the sun moves southward obviously, the temperature drops rapidly and the weather is cool. Water vapor close to the ground at night forms white dew on vegetation, hence the name "white dew".

16, autumnal equinox: On September 22-24, the sun moved to longitude 180 degrees, and the direct sunlight point returned to the equator, which is the midpoint of 90 days in autumn, and day and night became equal again. After this day, the days in the northern hemisphere get shorter and the nights get longer.

17, cold dew: 101October 8-9, the sun moved to 195 degrees. At this time, the direct point of the sun began to move south, the temperature in the northern hemisphere continued to drop, the weather was colder, and the dew in the forest was chilly, hence the name "cold dew wind".
