What kind of phenomenon occurs in the rainy festival?
The rain solar term is the second of the 24 solar terms, which falls on February 18-20 in the solar calendar every year. Rainy and solar terms, the temperature rises rapidly, the warm and humid air in the south becomes active, and gradually advances to the north, and meets the cold air in the north to form rainfall, and the rainfall begins. At this time, it's mainly light rain or Mao Mao rain, sometimes it's cold and sometimes it's hot, and then it's warm and cold.
The rainy season has entered the climate of spring. In most areas, everything is thriving, peaches and plums are in bud, cherries are in full bloom, geese fly back to the north from the south, and plants sprout. The chirping of the fruit is generally caused by the rising temperature in Xia Hou. When the weather is hot or stimulated, the fruit will scream.
Rain or fright, which solar term is January in the lunar calendar:
In today's 24 solar terms, rain follows beginning of spring, and beginning of spring is the second solar term in January of the lunar calendar, followed by fright and vernal equinox. This order is the same as the twenty-four solar terms recorded in pre-Qin and early Han documents such as Yi Zhou Shu Shi Xun Jie and Huainan Tian Zi Xun. However, in Records of Laws of Han Dynasty compiled by Ban Gu in the Eastern Han Dynasty, the order of the first four solar terms in spring is beginning of spring, sting, rain and vernal equinox, in which the order of sting and rain is just the opposite to the present order.
This calendar, which started with surprise and ended with rain, was used for a long time in the Han Dynasty. Zheng Xuan, a scholar in the Eastern Han Dynasty, commented on the Book of Rites, especially put forward that "the first month of the Han Dynasty was also marked with surprise. The February Festival in the Han Dynasty began with rain. " In ancient times, the former of the two solar terms in a month was called "Festival" and the latter was called "Zhong" or "Qi". So what Zheng Xuan meant by this passage was that since the Han Dynasty, the fright became the second solar term in the first month, and the rain retreated to the first solar term in February.
