What is the Millennium solar term?

The Millennium solar term is the fifteenth of the twenty-four solar terms.

The Millennium solar term is the end of the application of the moon in the dry calendar and the beginning of January. It marks the end of the Qiu Meng season and the beginning of the Mid-Autumn Festival. At this time, the crops began to mature, the autumn tiger gradually disappeared, and the temperature difference between morning and evening was large, especially at night. Therefore, there is a folk saying that "a thousand years are divided into nights, and one night is cold." The climate is relatively dry, and the precipitation in the north is obviously reduced.

During the Millennium, people had the custom of collecting clear dew. Li Shizhen's Compendium of Materia Medica in the Ming Dynasty records: "When there are many autumn dew, it can be collected in a plate and fried like a cake, which can prolong life and make people not hungry." Collecting dew has become the most special ceremony in the Millennium. In addition, there is the custom of offering sacrifices to Yu Wang in the Millennium. Yu Wang is the legendary hero of water control, Dayu. Fishermen on Taihu Lake call him "Waterway Bodhisattva".

The importance of the White Dew Festival

1. Climate change: The Millennium solar term is the watershed of the summer heat, which means the end of the summer heat. After entering the Millennium solar terms, the summer monsoon is gradually replaced by the winter monsoon, the cold air gradually goes south frequently, the temperature drops rapidly, and the temperature difference between day and night gradually widens. At this time, all parts of China began to fall in succession.

2. Crop growth: Dew season is the key period for crop maturity and harvest. At this time, the grain crops in the northern region began to mature, and the rice in the southern region gradually entered the harvest period. Therefore, the Millennium solar terms are of great significance to agricultural production.

3. Migratory birds migration: After the Millennium, migratory birds that are most sensitive to climate began to migrate collectively. Hongyan flies from the north to the south, and swallows fly to the south for the winter. Therefore, the Millennium solar term is an important period to observe the migration of migratory birds.
