What is the solar term reflected by the moonlit night?

The solar terms reflected by the moonlit night are: early spring.

It is said in the poem that "bloom is warm in spring" begins with "tonight", which shows that the poet is very sensitive to the changes of seasons and climate, and observes the subtle changes of nature with a pure heart.

The poet not only knows that spring is warm from the sound of insects, this is the poet's subtle feeling about tonight, and the sound of insects is just a phenology that coincides with his feelings. Describing the moonlit night in this way, the poet is sensitive to season, time and space, so he is unconventional and innovative.

This poem is about spring, not only from things like willow green and pink, but also from the night to cover up things that seem to have the most spring characteristics. It writes about the moon without detailing its light and shadow or lamenting its roundness. Instead, there is only half a moonlight at night, so that the night is not too thick and the moonlight is not too bright, resulting in a vague and harmonious melody.

Original text:

moonlit night

Author Liu, the Tang Dynasty

The moonlight is deeper than half a house, and the big dipper is withered south.

Tonight, through the green screen window, I know that spring is warm and the sound of insects is fresh.

Translation:

The night is still deeper, and the moonlight only illuminates half of the family, and the other half is hidden in the darkness.

The Big Dipper is tilted, so is Nandou. I didn't know the arrival of spring until tonight. Outside the screen window reflected by leaves, the chirping insects came to the house for the first time.
