"Twenty-four solar terms" is the product of ancient farming civilization, and farming production is closely related to the rhythm of nature. It is a knowledge system formed by ancient ancestors who followed the farming season and realized the changing laws of time (season), climate and phenology in a year (year) by observing the movement of celestial bodies.
"Twenty-four solar terms" said: "Go, go, the heat is over." "Chu" means termination, which means that the summer heat is about to pass, the summer heat will end on this day, and the temperature in most parts of China will gradually drop. Being in summer is not only different from mild summer, severe summer, slight cold and severe cold, but also represents the transition from hot to cold.
In China, the summer heat is divided into three periods: "The eagle is a sacrificial bird; Second, wait for the beginning of heaven and earth; Three Hou Wonaideng. " In this solar term, eagles began to prey on birds in large numbers; Everything between heaven and earth began to wither; "Henaideng" refers to millet, millet, rice and sorghum crops, and "Deng" means maturity.
The poem says: "As soon as the summer heat comes out, it is too late for the autumn wind to send you cool. On a day trip, under the oblique light of the south path, we cut the rice and drove through the horse pond. (Heshui Zuo) ",after the summer heat, except South China and Southwest China; The rainy season is coming to an end in most parts of our country, the precipitation is gradually decreasing, and the rice is ripe and harvested. Especially in North China, Northeast China and Northwest China, we must pay close attention to water storage and moisture conservation. If there is drought during autumn sowing, the sowing date of winter crops will be postponed.
Summer custom activities:
1, travel to welcome autumn
The folk customs around the summer solar terms are mostly related to ancestor worship and welcoming autumn. There will be folk activities to celebrate "July 30th" around the summer vacation. In addition, after summer, autumn is getting stronger, which is a good time for people to go swimming in the suburbs to meet autumn scenery. After the heat, even the clouds in the sky seem to be evacuated and free, unlike the thick clouds in the heat. There has always been a saying among the people that "seeing a clever cloud in July and August" means "going out to welcome autumn".
2. River lanterns
River lanterns, also known as "lotus lanterns", usually put lights or candles on the base, and put them into rivers, lakes and seas during the Mid-Autumn Festival to let them float. River lanterns are for ghosts such as drowning in Purdue water. A passage in Xiao Hong's Biography of Hulan River is the best annotation to this custom: "July 15th is Ghost Festival; You damn fool can't keep alive, and it's hard to wander in hell. They want to support themselves, but they can't find the direction. On this day, the dead fool holds the river lantern and has to support it for a lifetime. "
3. Fishing Festival
For coastal fishermen, the summer heat is the harvest season. During the summer vacation every year, the annual grand fishing festival will be held in the coastal areas of Zhejiang. It was decided to hold a grand fishing ceremony on the day of the fishing moratorium in the East China Sea to see the fishermen off to sea. The 9th China Fishing Festival was held in Xiangshan County, Zhejiang Province on September 6th, 2006. Because, at this time, the water temperature in the sea area is still high, fish will still stay around the sea area, and fish, shrimp and shellfish will mature. Therefore, from this time on, people can often enjoy all kinds of seafood.
