Bai Dew is the 15th of the 24 solar terms and the third of the autumn solar terms. Bai Dew is an important festival reflecting the growth of cold in nature. As the weather gradually turns cooler, the sun is still hot during the day, but the temperature drops quickly in the evening, with a big temperature difference between day and night. When it comes to Bailu, summer winds are gradually replaced by winter winds, and the cold air turns into an attack, so the temperature drop is also gradually accelerated. The white dew basically ends the stifling heat of the summer days, and the weather gradually turns cooler and colder, and the dew condenses. The ancients used the four seasons to match the five elements, autumn is gold, golden white, white to describe the autumn dew, so the name Bai dew.
The ancient Chinese, based on their observation of nature, divided the Bai Dew into three periods: The first is the arrival of the wild geese, the second is the return of the birds, and the third is the return of the birds to their shame. This means that during this season, migratory birds such as geese and swallows fly south to avoid the cold, and birds start to store dry fruits and grains for the winter. At this time, farmers are also busy harvesting crops, as the saying goes, grab the autumn grab the autumn, not to grab the loss. During the period of Bai Lu, folk customs around the world, mainly sacrifices to Dayu, brewing grain wine, drinking Bai Lu tea, etc..
Bai dew represents the change from hot to cool, and everything grows with the cold air, gradually falling and maturing. The White Dew season is a very busy time across China. In the northeast, the harvest of grain, sorghum and soybeans, some places began to pick new cotton; at the same time, to cotton, corn, sorghum, grain, soybeans and other seed selection and seed retention, timely stubble, land preparation, fertilizer delivery, to plant wheat. North China, at this time is also a busy autumn harvest season, a variety of large autumn crops have matured, began to harvest; autumn harvest at the same time, but also to tighten the delivery of manure, plowing, leveling the land, etc., early preparatory work for planting wheat. In the northwest, sowing of winter wheat begins. The southwestern region to the white dew season, everywhere present a busy scene, because the white dew white blanket, grain full of yellow rice and grain have to hurry up to harvest. Late autumn crops such as corn, sweet potatoes, etc. have to strengthen field management to promote its early maturity and avoid the damage caused by low temperature frost. In central China, catching time to harvest late and middle rice, summer corn also started to harvest, cotton also picked in batches, and late corn had to strengthen water management. Besides, we have to make good use of the time to level the land and prepare for the planting of wheat.
