As soon as the solar terms in the long summer are equal, the emperor welcomes the summer and prays for a bumper harvest.

The long summer is a symbol of climate change and a hint of the arrival of summer. Since the long summer, the sunshine time is getting longer and longer, and the temperature is rising. When people's clothes start to change into short sleeves, it means that the long summer is coming. In ancient times, the arrival of long summer was marked by the continuous chirping of crickets, and the "crickets' sound" in long summer awakened the tranquility of early summer.

Wait for the sound.

People divide the long summer into three parts, and then the mole's voice. The description of the mole in the Book of Rites and the Moon Order is like this: "The mole is a frog." You Zhu, a scholar in Qing Dynasty, once wrote in Yi Xun Shi: "Cockroaches are frogs. In February, frogs began to sing, and those who sing in summer are small in size and brown and black in color, and can sing in shallow water. " However, seventy-two episodes of the Moon Order hold that cricket refers to the cricket in the soil where the cave was born. The third class of Changxia said this: On the day of Changxia, the worm came out on the fifth day, and the fifth king melon was born. That is to say, every five days is a waiting period, and the long summer time is from May 5 to 7 in the solar calendar every year, so we can add five days to this time to calculate each time of the long Xia San waiting period.

The custom of welcoming summer in ancient times

Ancient science and technology were not very developed, and the harvest of people planting plants depended on the weather. Therefore, in the long summer, people attach great importance to the changes of weather and solar terms. "The Book of Rites and the Moon Order" records: "The son of heaven lives in the left hall, takes Zhu Dao, drives the red flag, wears red clothes and presents ruby. ...... Three days before the long summer, Maharashtra's son said: One day in the long summer, Shengde was on fire. The son of heaven is Qi. On the day of long summer, Tianzishuai welcomes summer in the southern suburbs. Reward, reward, and seal the princes. When you celebrate the ceremony, you are all happy. " During the Zhou Dynasty, on the long summer day, the emperor personally led hundreds of civil and military officials, dressed in red and red jade, to the suburbs to "welcome the summer" to express his wish for a bumper harvest, and sent officials to various places to "order farmers to work hard, not to rest in the capital, and not to delay time."

What is a long summer?

In ancient times, people's understanding of long summer was long summer and late spring, and it was also a season of vigorous growth of plants. Among the 24 solar terms: "Long summer, April Festival. Make a word to understand spring. Summer, holidays. At this time, everything is fake and big. " Astronomically, Chang Xia said that bidding farewell to spring is the beginning of summer. When the temperature rises obviously, the summer heat comes, thunderstorms increase and crops enter the peak season, people are used to taking long summer as an important solar term.
