What do you mean by heavy snow and light snow cooking nonstop?

Heavy snow, light snow and endless cooking are all about the dead of winter.

Heavy snow is the third solar term in winter, marking the official start of the mid-winter season. After the solar term of heavy snow, the days are getting shorter and the nights are getting longer and longer. The folk proverb "heavy snow and light snow, endless cooking" describes that a day is so short that people almost have to cook three meals in a row.

After the solar term of heavy snow, the dawn is later and the darkness is earlier. I feel that the days are getting shorter and shorter and the nights are getting longer. Until the next solar term, the winter solstice, after the winter solstice, it slowly dawned early and got dark late.

In the summer solstice, the day is the longest and the night is the shortest. After the summer solstice, the days get shorter and the nights get longer. Cycle after cycle, four seasons change. The arrival of heavy snow solar terms means that the temperature drops obviously and the precipitation increases. The most common festivals at this time are cooling down, raining or snowing.

Reasons for shortening the time:

This is related to the direct position of the sun. As we all know, the earth revolves around the sun, and its axis of rotation is tilted by 23.5 degrees. It is because of this tilt that we can feel the changes of the four seasons. When the earth revolves to a certain position, the northern hemisphere is farthest from the sun and the southern hemisphere is closest to the sun. This is the solstice of winter.

As the earth continues to rotate, the northern hemisphere gradually approaches the sun and the southern hemisphere gradually moves away from the sun. At this time, it is the vernal equinox. The period between the winter solstice and the vernal equinox is what we call midwinter.

In midwinter, the direct position of the sun deviates more from the surface of the earth. This means that the sun's rays need to travel a longer distance to reach the earth's surface, so the rays will become more scattered and weak. As a result, the time of day becomes relatively short.
