Which ancient poem describes the scenery of Xiaoxue?

Ancient poems sprinkled with mica powder describe the scenery of light snow.

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 wide range of cold air going south, which will bring a wide 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 visible distance is equal to or greater than 1000m, the ground snow depth is less than 3cm, and the snowfall in 24 hours is between 0. 1-2.4mm, which 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. For example, the solar term with the largest annual snowfall in the middle and lower reaches of the Yellow River and its vicinity is neither "light snow and heavy snow" nor "slight cold and severe cold", but a "rainy" solar term in spring.

Xiaoxue's farming activities:

During the light snow solar term, farmers all over the province seize the farming season and do a good job in harvesting, sowing and cold protection management. At the beginning of the light snow solar term, the frozen depth of the soil in Northeast China has reached 10cm, with an average of 1cm for almost one day and night, and more than one meter at the end of the solar term. Therefore, as the saying goes, "the snow area is tightly sealed", and then rivers of all sizes freeze.

An agricultural proverb says that a light snow will bring a bumper year in the coming year. There are three meanings here. First, there will be light snow, and the rain will be even in the coming year, without major droughts and floods; Second, snow can freeze some germs and pests to death, reducing the occurrence of pests and diseases in the coming year; Thirdly, snow can keep warm, which is conducive to the decomposition of soil organic matter and enhance soil fertility.
