Until Bailu, the summer monsoon was gradually replaced by the winter monsoon, and the cold air turned from the defensive to the offensive. In addition, the direct sunlight point moved southward, the sunshine time in the northern hemisphere became shorter, the light intensity weakened, and the ground radiation dissipated heat faster, so the speed of temperature decline gradually accelerated. Bailu has basically ended the muggy summer weather, and the weather has gradually turned cool, cold and dew. The ancients used four seasons with five elements. Autumn is golden, golden and white. It is white to describe autumn dew, so it is called "Bailu".
According to the observation of nature, the ancient Chinese divided Bailu into three stages: "One stage is when the wild geese come, the second stage is when the black birds return, and the third stage is when the birds raise shame." This means that during this solar term, the wild geese, swallows and other migratory birds fly south to escape the cold, and the birds begin to store dried fruit and grain for winter. At the moment, farmers are also busy harvesting crops, which is the so-called "grab autumn, grab it, or lose it". Folk customs in various places during the period of Bailu mainly include offering sacrifices to Dayu, brewing grain wine, drinking Bailu tea, etc.

Twenty four seasonal songs
At the beginning of spring, the sun turns and the rain flows along the river;
Waking crows cry, and the skin dries at the vernal equinox;
The Qingming Festival is busy planting wheat, and the grain rain is planting fields.
The goose feather lives in the beginning of summer, and the small full sparrow comes to the whole;
May Festival of awn seed, no cotton in summer solstice;
Light heat is not hot, but severe heat is dog days.
In the beginning of autumn, I was busy fighting indigo and drying tigers in the summer;
White dew and smoke are put on the shelf, and there is no field on the autumnal equinox;
The cold dew is not cold, and the frost has changed the sky.
The beginning of winter is October, and the snow is sealed tightly;
On the fork of the snow river, there is no boat on the winter solstice;
The mild cold enters the December, and the severe cold lasts another year.
The seventy-two marquis corresponding to Bailu is that on the day of Bailu, the geese come, the black birds return five days later, and the birds raise shame five days later.
Seventy two marquis is a calendar supplement used to guide agricultural activities in ancient China. It is compiled according to the geography, climate and some natural scenes of the Yellow River basin. It is based on five days, three seasons, six seasons and four seasons. There are 72 seasons in a year. Each weather corresponds to a phenological phenomenon, which is called "waiting". Among them, plants are supposed to sprout, blossom, and bear fruit;
