What is the meaning of the long summer solar terms?

When people are in the long summer, they will hold a "Welcome Summer" ceremony, which has a harvest prayer and beautiful meaning. The long summer also indicates the change of seasons and the official start of the summer season. Long summer is the seventh solar term in the twenty-four solar terms of the lunar calendar, and it is also the first solar term in summer. When the sun reaches 45 degrees of the Yellow Meridian, it is a long summer, and the date is May 5 or May 6 of the Gregorian calendar every year. After the long summer, the temperature in southern China rose rapidly, and the rainfall and the number of rainy days increased significantly, which became an important solar term in the peak season of crop growth.

Chang Xia said that saying goodbye to spring is the beginning of summer. Spring comes and summer grows, autumn harvests and winter storage, and in the long summer, everything is thriving. Because China has a vast territory and a large span from north to south, natural rhythms vary from place to place. In the long summer season, only the area south of Fuzhou-Nanling line in China enters the real summer of "the trees grow dark in summer and the balcony reflects into the pond"; And parts of the northeast and northwest just have the breath of spring at this time. According to the classification standard of modern climatology (climate average temperature) in China, the daily average temperature rises steadily to above 22℃, starting in summer.
