What are the implications and traditions of the long summer solar terms?

Implication and tradition of the long summer solar term: the implication of the long summer solar term is to formally enter summer, when not only the temperature will start to rise, but also the rainfall will start to increase, and crops will enter a vigorous growth stage. There are many traditional customs of solar terms in long summer. Among them, long summer needs to eat long summer eggs, which helps to improve children's appetite. Long Xia also has a tradition of calling people names, saying auspicious words while calling people names.

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.

After the long summer officially entered the rainy season, rainfall and rainy days increased significantly. Summer is the best season for many crops to grow vigorously. Adequate light, suitable temperature and abundant rain provide necessary conditions for plants. In summer, affected by the warm and humid air flow from the ocean, the southern region is generally hot, humid and rainy. Qinling-Huaihe river basin is a transitional area between rainy south and rainy north. From the vicinity of Huaihe River in Qinling Mountains to the north, the rainfall decreased sharply.

After entering the long summer solar term, the rainfall in the middle and lower reaches of the Yangtze River and South China increased rapidly in mid-May, and at this time, South China also entered the peak period of the first flood season. The rainstorm at this time often has the characteristics of continuity in time, extensiveness in region and fierceness in intensity. In the Pearl River system of Guangdong and Guangxi and the Minjiang River system of Fujian, the highest annual water level often appears in this period, and there is a folk saying that "the summer is long, the river is full, and the river is full".
