Characteristics of ancient solar terms

It means to begin to enter the spring, "yang and thorns, everything is spring." After beginning of spring, everything is full of vitality, and the four seasons begin now.
Rain: finger fights. The longitude of the sun is 330 degrees. At this time, the spring breeze blows all over, the ice and snow melt, the air is moist, and the rain is increasing, so it is called rain. People often say: "Spring blossoms, and rain is busy to send fertilizer."
Stunned: fight with your fingers. The longitude of the sun is 345 degrees. This solar term means that after the beginning of spring, the weather will get warmer, the spring thunder will start to sound, and all kinds of hibernating animals that are dormant in the soil will wake up and start to move, so it is called a fright. During this period, the eggs laid by overwintering insects will also begin to hatch. Some parts of China have entered the spring ploughing season. As the saying goes, "After being shocked, it is warm and harmonious, and the old toad sings folk songs." "I was startled by a plow, and the vernal equinox was full of air." "Before the thunder comes, the rain is like a dragon."
Vernal equinox: fighting refers to shackles. The yellow meridian of the sun is 0 degrees. The sun is above the equator at the vernal equinox. This is the midpoint of 90 days in spring. On this day, the northern and southern hemispheres are equal in day and night, so it is called the vernal equinox. After this day, the direct position of the sun moves northward, and the days in the northern hemisphere are long and the nights are short. So the vernal equinox is the beginning of spring in the northern hemisphere. Overwintering crops in most parts of China have entered the spring growth stage. Agricultural proverbs in various places include: "The spring equinox comes first, and rice competes for money" (Guangdong), "The spring equinox never stops raining, but the summer equinox never stops burning" (Sichuan), "When it rains, every family is busy, planting melons and beans first, then transplanting them" (Hubei), "Planting vegetables at the spring equinox, picking melons in summer" (Hunan) and "Planting beans at the spring equinox, and planting them at the autumn equinox.

Before and after sowing, the rainfall in the middle and lower reaches of the Yangtze River in Central China increased and the temperature rose. In the rainy season, the air is very humid, the weather is extremely sultry, and all kinds of utensils and clothes are prone to mildew, so it is called "Huangmeitian" in the middle and lower reaches of the Yangtze River in China.
Summer solstice: Beidou points to B. The yellow meridian of the sun is 90 degrees. When the sun is at the 90-degree "Summer Solstice Point" of the Huangjing, the sun is almost directly above the Tropic of Cancer, and the sun is the highest at noon. This day is the longest day and the shortest night in the northern hemisphere. From this day on, it entered the hot season, when everything in the world grew most vigorously. In ancient times, the heart also called this day the northern solstice, meaning the northernmost day when the sun was born. After the summer solstice, the sun gradually moves southward, and the days in the northern hemisphere become shorter and the nights become longer.
