Rhetoric of solar terms

The field scenery in October is charming, like a beautiful picture scroll. In the early morning, it was all white and foggy, hanging over the fields like gauze fog, as if to give the rice the last moisture. When the sun came out, the eyes were golden, and the full ears of rice bowed their heads and bent the rice stalks. Dewdrops hung on the rice grains, shining in the sun, giving off dazzling light, like countless pearls. A gust of wind blows, and the rice flutters with the wind, making a rustling sound, just like the approachable laughter of farmers.

Autumn: Autumn is the third season among the four seasons, and it is the transition season from summer to winter. The lunar calendar is from beginning of autumn in July to beginning of winter in September, the solar calendar is from 9 to 1 1, and the astronomical cycle is from the autumnal equinox to the winter solstice. The phenological criteria studied by meteorologists are: after the summer heat, it is considered as autumn when the average temperature for five days is stable below 22 degrees, and it ends when it is below 10 degrees. There are six solar terms in autumn, namely beginning of autumn, Chushu, Bailu, Autumnal Equinox, Cold Dew and First Frost. The temperature will gradually drop in autumn, but it is generally slower than in winter. Due to the difference of dry and wet conditions, there will be cold and rainy weather conditions or dry and cool weather conditions in different regions. In the cold late autumn, due to the large temperature difference between day and night, the water vapor transpiration during the day will condense at night, either dew or frost.
