What is the difference between beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew and First Frost?

Beginning of autumn: The summer solstice is cool, and autumn begins. Autumn means that plants are about to mature, and then the temperature drops gradually. Summer: It means that the summer heat will soon pass, and the summer heat will end on this day, and the temperature will gradually drop in most parts of China. White dew: At this time, because it is cool at night, the water vapor near the ground condenses into white dew on plants and other objects, which means the weather turns cold.

Autumnal Equinox: This is the midpoint of 90 days in autumn, and day and night are equal again. After this day, the days in the northern hemisphere get shorter and the nights get longer. Cold dew: the temperature continues to drop, and the dew is cold at night, which means that the climate will gradually change from cold to cold. First frost: The weather is getting colder, and first frost begins. In the area south of south latitude, the average temperature is mostly 65438 06℃.
