Characteristics and custom origin of long summer solar terms

"Long summer" means "big", which means that the plants sown in spring have grown upright.

At a deeper level, the 24 solar terms reflect the change of "Qi" in the four seasons, and the change of Qi is related to the change of natural rhythm. In the long summer, the yang is getting longer and longer, and everything grows sturdily with the rise of the yang.

Chang Xia said that bidding farewell to spring is the beginning of summer, so it is also called "the end of spring".

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.
