Which ancient poem describes a little snow ant?

Ant describes Xiaoxue's ancient poem: mica powder is scattered all over the world.

Lu Wengui, a writer in the Yuan Dynasty, wrote "Sudden cold and light snow in late October", which said: mica powder is scattered all over the world, and the world is called red bean paste ash. He compared snow to white and bright "mica powder", but people called it "bean cake ash", which means the year of Dafeng.

Light snow is a solar term reflecting precipitation and temperature, and it is a solar term with high frequency of cold wave and strong cold air activity. Light snow solar terms indicate that a relatively stable meridional circulation has been established in East Asia. When the Siberian depression or trough moves eastward, there will be a large range of cold air going south, which will bring a large range of windy and cool weather.

There is no necessary connection between the light snow in solar terms and the light snow in the weather. The meaning of "light snow" in solar terms is different from that in daily weather forecast. Light snow solar term is a climate concept, which reflects the temperature and precipitation. The "light snow" in the weather forecast refers to the snow with less snowfall intensity.

Meteorologically, the horizontal visual distance is equal to or greater than 1000 meters when it snows. Snow with a depth of less than 3 cm and a snowfall of 0. 1-2.4 mm in 24 hours is called "light snow". Light snow solar terms do not necessarily snow. In fact, the solar terms with the largest snowfall in the whole year are not in light snow and heavy snow.
