Lixia is the 7th solar term among the 24 solar terms in the lunar calendar, and the first solar term of summer, indicating the official start of the Mengxia season; When the sun reaches 45 degrees of the ecliptic meridian, the beginning of the summer season is celebrated. Dou refers to the southeast, and Wei is called Li Xia. Everything grows up here, hence the name Li Xia.



Introduction to solar terms
Li Xia · One of the 24 solar terms

In the "Interpretation of the Seventy Two Seasons of the Moon", it is said: "From the beginning to the beginning, from summer to summer, all things are false and large until now." Here, "false" means "large", which means that plants sown in spring have already grown upright.
In fact, if according to the standard of climatology, summer begins when the daily average temperature steadily rises above 22 ℃. Before and after the "beginning of summer", only the areas south of the line from Fuzhou to the Nanling Mountain have the real summer of "thick overcast trees and long summer days, while some areas in the northeast and northwest have just entered spring. The average temperature in most parts of the country is around 18~20 ℃, which is the midspring and late spring season of" red and purple against beautiful ". In May, many places have locust flowers blooming.
At the beginning of summer, everything is flourishing. In the book "Eight Killings of Lotus" by the Ming Dynasty, it is written: "On the day of Mengxia, heaven and earth begin to intersect, and all things are beautiful." At this time, summer harvest crops enter the late stage of growth, winter wheat blooms and fills the grain, rapeseed is close to maturity, and the annual scenery of summer harvest crops is basically determined. Therefore, there is a saying in agriculture that goes, "Look at summer at the beginning of summer. The management of rice planting and other spring crops has also entered a busy season.
So, China has always attached great importance to the Li Xia solar term in ancient times. According to records, during the Zhou Dynasty, on the day of the beginning of summer, the emperor personally led civil and military officials to the outskirts to "welcome summer" and instructed officials such as Situ to go to various places to encourage farmers to work hard.
