What does 24 times Hua Xinfeng mean?
Twenty-four times in Hua Xinfeng and twenty-four times in Hua Xinfeng are also called twenty-four winds, so they are called faithfulness because they come from flowering period.
The so-called Hua Xinfeng refers to the flowers that bloom in a certain solar term. Because it is the wind from flowering period, it is called trade wind. People choose a flower with the most accurate flowering period as the representative. This solar term is called Hua Xinfeng, which means the weather that brings flowering news.
According to The Old Story of Jingchu in Zonggu of Southern Dynasties, the plum blossom begins and the neem flower ends, and it goes back to Hua Xinfeng every twenty-four times. That is to say, from the slight cold to the * * * Eight Qi (eight integrity periods) in Grain Rain, one hundred and twenty days, every five days is a waiting period, counting 24 days, and each waiting period should be a flower letter. In Hua Xinfeng, there are two solar terms every month, and each solar term has three periods, each lasting five days. Every five days, there is a flower letter, that is, every five days, there is a flower in full bloom, that is, Hua Xinfeng waits for two days in January. Whenever Hua Xinfeng is waiting for flowers to bloom, flowers are in full bloom around Grain Rain, with colorful fragrance everywhere and spring everywhere. Azadirachta came last, indicating that Azadirachta was over. After 24 romantic journeys, the long summer begins.
As the saying goes, "when flowers and trees are in season, birds sing to announce agricultural time." Flowers, trees, birds and animals in nature all move according to certain seasons, and their activities are closely related to climate change. Therefore, their activities have become the symbols of seasons, such as the bud, leaf development, flowering, fruiting, yellow leaves and deciduous leaves of plants, dormancy, resuscitation, first sound, reproduction and migration of animals, etc. These are all related to climate change. People call these rhythmic natural phenomena phenology.
In The Book of Songs, "April Shura, May Mi Ming", "July Liuhuo", "August Jujube Peeling, October Rice Harvest" and so on are all phenological manifestations.
Phenology is closely related to agricultural time. China is the first country to study phenology in the world. The earliest monograph on phenology and summer in the early years of the Western Han Dynasty recorded phenology, meteorology, astronomical phenomena and important political and agricultural activities, such as farming, sericulture and horse breeding, in the order of twelve months a year. Since then, there have been similar phenological records in Lv's Spring and Autumn Annals and The Book of Rites, which gradually developed into 24 solar terms and 72 phases a year.
There are also 24 records about Hua Xinfeng in Guangfang Qunpu written by Emperor Kangxi of Qing Dynasty. Cheng Quanchang's "Dew Can't Be Exposed" once said, "Flowers bloom in March, and the style of flowers is different"; Lu You's "You Qian Shan" also has a description of the flower trade wind, in which "the sound of a sudden earthquake starts, and the wind hears that flowers bloom".
