Is it better to rain on the solstice in summer or not to rain?

The rain in summer is like an award-winning scholar. This proverb is a figurative sentence, and its meaning is easy to understand. This is a metaphor for the summer solstice rain to illustrate the importance of rain to the summer solstice. In the past, it was very rare for a scholar to be promoted, but it is also very rare if it rains from summer to Sunday. From another perspective, the importance of rain to the summer solstice is self-evident.

From the point of agricultural planting, summer crops have been sown in North China and Huanghuai area from summer to the future. At this time, it is in the hot season, the temperature is high, and the field is prone to drought. If it rains at this time, it will promote the growth of seeds and seedlings and lay a good foundation for subsequent high yield. Therefore, from this proverb alone, it is a better result that it rains on the solstice in summer.

The summer solstice is the 10 of the 24 solar terms. Fighting means noon; The yellow meridian of the sun is 90 degrees; June 2 1~22 of Gregorian calendar. On the day of summer solstice, the position where the sun shines directly on the ground reaches the northernmost part of the year, almost directly on the tropic of cancer. At this time, the daylight hours in all parts of the northern hemisphere reach the longest in the whole year. For the Tropic of Cancer and its northern region, the summer solstice is also the highest day at noon in a year.

The solstice in summer is the turning point of the sun's northward movement. After the summer solstice, the direct point of the sun began to move south from the Tropic of Cancer, and the days in the northern hemisphere began to shorten gradually. For the area north of the Tropic of Cancer in China, the height of the noon sun begins to decrease day by day from summer to the future. For the area south of the Tropic of Cancer in China, the height of the sun returns to the south from summer to noon in the future, and it begins to decrease day by day after the sun shines again.
