What are the omens before it snows?

Signs before snow: cloudy to cloudy. The wind blows first, then gradually becomes smaller, and the snow slowly falls.

In the mixed cloud, due to the existence of ice water, ice crystals continue to condense and grow into snowflakes. When the temperature under the cloud is below 0℃, snowflakes can always fall to the ground to form snowfall. If the temperature under the cloud is higher than 0℃, sleet may appear. Snowflakes have many shapes, such as star, cylinder and flake, but the basic shape is hexagon.

Medicinal value of snow;

According to Chinese medicine, it is said that snow storage can protect vegetables, wheat and locusts. If it is used to soak grains, it can resist drought and not produce insects, and it can also seal the jar and pickle vegetables. According to Compendium of Materia Medica, Laxue can really clear away heat and detoxify. Applying it to the affected area can relax muscles and promote blood circulation, and can cure burns and prevent frostbite. It is also necessary for celebrities to cook tea.

Due to the serious industrial pollution in modern society, especially the air pollutants attached to the first snow, it is inedible and usually not used as medicine. Since then, the continuous snow should be relatively clean, microorganisms and bacteria "dormant", and the nitride content is higher than that of ordinary water, which is easy to absorb and contributes to metabolism. Its taste is sweet and cool, and it also has a certain effect on heatstroke prevention and malnutrition in summer after storage.
