1, after the Millennium is the autumnal equinox solar term. The autumnal equinox is the sixteenth solar term in the twenty-four solar terms of the lunar calendar, usually on September 22-24 of the Gregorian calendar every year. The climate in the south began to decline from this solar term. First, the sun arrived at 180 (autumnal equinox) on this day, and the sun almost directly hit the equator of the earth, and the length of day and night is equal all over the world (regardless of the refraction of sunlight by the atmosphere and the shadow in the morning). After the autumnal equinox, the direct point of the sun continues to move from the equator to the southern hemisphere. The northern hemisphere has short days and long nights (short days and short nights), while the southern hemisphere has long days and short nights (long days and short nights). Therefore, the autumnal equinox is also called the landing point.

Second, the mysterious birds return: Swallows and other migratory birds fly south to avoid the cold. At three o'clock, the birds were ashamed: Hundred birds began to store dried fruits and grains for the winter.
