First,

In the golden autumn, frost falls in October,

the flowers wither and the grass withers and turns yellow.

A group of wild geese are flying to the south for company,

The fallen sycamore leaves are sad and desolate.

Second,

A night of early frost in the west wind,

The remaining lotus weeps and sits on the cold pond.

The sparse trees and the cold moon are my companions,

I am lonely and longing for my hometown.

Third,

The autumn wind blows, the fog condenses,

the grass fades and the trees turn yellow,

the cinnamon seeds are fragrant and the chrysanthemums are blooming. Proud,

Hundreds of stings are hidden in the cave.

Historical origin

Frost is the last solar term in autumn and is the transition from autumn to winter. In the frost season, all things are completed and completed in Xu. The sun sinks into the earth and the yin energy begins to condense. The cold weather begins with frost.

"Yi Zhou Shu·Zhou Yue": "The middle Qi of autumn in March are: summer heat, autumnal equinox, and frost." Wang Chong of the Eastern Han Dynasty said in "Lunheng": "Clouds and mist are signs of rain, and dew is the sign of summer. In winter, it is frost, when it is warm, it is rain, when it is cold, it is snow. Rain and dew all come from the ground, not from the sky."

Whether it is dew or frost, "it all comes from the ground. "It doesn't fall from the sky." How can it be called frost? In fact, the name "Frost" is just used to describe the climate characteristics of "sudden temperature drops and large temperature differences between day and night" during this season. Since "frost" is a sign of cold weather and large temperature differences between day and night, this season is named after "frost", which means "a sudden drop in temperature and a large temperature difference between day and night".

The "Frost Descent" solar term reflects the climate characteristics of gradually getting colder. It does not mean that "frost will fall" when entering this solar term. In fact, "frost" does not fall from the sky. "Frost" is formed when water vapor on the ground condenses when it encounters cold air due to changes in temperature. The "Frost Descent" solar term has nothing to do with "Frost Descent".
