The whole ancient poem Cold Night.

Crows fell on the moon, crowed coldly, slept on maple trees, and slept in fishing lanes by the river.

In the lonely Hanshan Temple outside Suzhou, the bell that rang in the middle of the night reached the passenger ship.

Translation:

The moon is silent, crows crow from time to time, and autumn frost fills the sky. Looking at the maple trees and fishing fires on the river, I was too depressed to sleep. Late at night, under the dim light, the bell of Hanshan Temple outside Suzhou reached my fishing boat.

The author of this poem is Zhang Ji (about 7 15~ about 779), named Sun Yi, a poet in the Tang Dynasty, and a native of Xiangzhou (now Xiangyang County, Hubei Province). The full name of this poem is night parking near Fengqiao.

Extended data:

The settlement of the moon in Frost Night: here refers to the dawn; Five bodies: here refers to the crow's cry; Frost all over the sky: The poet Zhang Ji mistook ice fog for frost.

Meteorology, fog refers to a large number of water droplets or ice crystals suspended in the air near the ground, making the horizontal visibility less than1km; Frost is a white ice crystal formed by direct condensation of water vapor in the air on the ground or ground objects.

Obviously, fog refers to the condensation of water vapor in the air, which can be water droplets or ice crystals; Frost only refers to the surface solid condensation of water vapor. When the poet stayed in Qiao Feng at night, it was cold and foggy. The fishing fire reflected by ice crystals and the light of moonlight (or the afterglow of the moon) enter the poet's eyes, and he thinks it is the light reflected by frost.

During the Tang Dynasty 1000 years, people's understanding of many natural phenomena was superficial. They either refer to the ice fog in the air and the frost on the ground as frost, or think that the frost on the ground is formed by "frost" landing in the air. The first frost is one of the 24 solar terms, hence the name. Therefore, it is logical for Zhang Ji to use "frost all over the sky".
