It doesn't snow much.

Heavy snow does not snow, and food is as solid as iron.

What does this sentence mean?

In rural areas, people are very concerned about the changes of solar terms, which are closely related to agricultural life and production. Under normal circumstances, there will be heavy snow after the solar term. The heavy snow mentioned here is the snowflake falling from the sky. After the solar term, there is often heavy snow. Farmers like to see heavy snow. They think it is a good year.

According to the experience of farmers, the snowy winter always indicates a good year in the coming year, and the weather in winter is cold. After the snow melts, it will completely enter the soil and rarely evaporate, which provides a strong guarantee for the next year's spring ploughing.

If there is no heavy snow after the solar term, people will worry that the next year's harvest will be poor and the land will be dry, which is naturally not conducive to the germination and growth of crops. Therefore, there is a saying that "heavy snow does not snow, and food is as solid as iron".

Grain is as solid as iron, which means that grain becomes scarce, that is, the grain harvest is poor. This sentence exaggerates the scarcity or reduction of food.
