Composition about the 24 solar terms in the second volume of the second grade of primary school

Jěng zhé is the third of the 24 solar terms. On March 5th and 6th, every year, when the sun reaches 345 degrees, it is "in a daze". Sting means that when the weather gets warmer, the spring thunder begins to sound, awakening the insects that are dormant and hibernating underground. "Sting" means hiding. "Twenty-four solar terms" said: "February Festival, everything vibrates, and when it vibrates, it thunders, so it is called thunder. It's an escaped cockroach. "Tao Yuanming, a poet in the Jin Dynasty, said in a poem:" During the spring rain (gü u), the east corner (yú) began to thunder, which shocked people. "In fact, insects can't hear thunder. Spring is back, and the warmer weather is the reason why they end their hibernation and "run away in surprise". In China, the time when the spring thunder begins to ring varies from place to place. On the average for many years, thunder can be heard in southern Yunnan around the end of 1, and the first thunder day in Beijing is in late April. The saying that "thunder begins with you" is consistent with the climate law in Jiangnan.

"Smell" is a season that reflects phenology. It's the first half of March in the solar calendar, and the weather is getting warmer. Spring thunder began to shake, and hibernating animals and various insects dormant in the dormant soil felt the warmth and shock of spring. In this festival, the land in northern Shandong is completely thawed from September 9 to September 9, with the temperature generally at 4 ~ 5℃ and frequent cold waves. Maximum temperature 18 ~ 23℃, minimum temperature -3 ~ 7℃. The precipitation is generally 3 ~ 5 mm, sometimes more than 20 mm, and sometimes less than 1 mm.

In this season, the phenomenon of "cold spring" in the south of the Yangtze River will last until the last few days of fright, while the cold climate in the north will last longer, so "spring cover" is still very important in this solar term. Especially for the elderly, don't cut too little clothes just because the weather is getting warmer this solar term. Clothes should increase or decrease with the climate change. At this time, the liver qi is strong, and the elderly are prone to get angry. Pay attention to the adjustment of mood and consciousness, keep calm at any time, and don't get angry, otherwise the liver qi will rise too much, which is easy to dizziness and stroke. This solar term should be washed with medlar soup to keep the skin shiny.
