Stunned:

"This is the third of the 24 solar terms and the beginning of the mid-spring season. The weather gets warmer, the rain increases, and the animals that have been dormant for a winter gradually wake up.

Fan Chengda in the Southern Song Dynasty wrote "Floating Clouds in Qin Louyue".

Dark clouds are gathering and the light thunder is faint. At first, I was shocked, stung, the tortoise was angry, and the green wind was anxious. The jade stove smells like smoke, and the wall is thick and wet. Yan Zhi is wet, the flower tips are gone, and the painting building stands tall.

The Millennium is frost.

The Millennium solar term is the beginning of the Mid-Autumn Festival, and it is also an important festival to reflect the temperature change.

After the Millennium, the sky is high and the clouds are light, and the air is cool and cool. You can obviously feel the cool autumn coming.

Speaking of the Millennium, we have to mention a poem by Du Fu, a poet in the Tang Dynasty: How bright the moonlight is at home! .

Remembering my brother on a moonlit night-(Tang) Du Fu

A vagrant heard the drums heralding the battle, which was the first call of a wild goose on the border in autumn.

The dew turns to frost tonight, and the moonlight at home is bright!

Brothers are scattered, and no one can ask about life and death.

Letters sent to Luoyang city are often not delivered, and wars often do not stop.

There is also a solar term hidden in this poem, which is the Millennium.

The poet Du Fu expressed his strong feelings with the method of "word order inversion". From this evening on, he knew that the dew tonight would be first frost, and it was chilling to enter the Millennium solar terms.

Autumnal equinox:

Liu Yuxi's poem "Xiqiao is flat day and night, why does it stop at noon?" It is the autumnal equinox. On this day, the day is as long as the night, equally divided.
