What did the ancients do in the cold season?

During the severe cold, the ancients collected ice cubes.

In ancient times, there was no technology to make ice. In ancient times, ice cubes were taken down from the mountains, covered with thick cotton cloth to prevent contact with the outside heat, and stored in the cellar. In ancient times, wealthy families and royalty had special ice rooms to store ice cubes. When it freezes in the cold river, they ordered people to collect ice cubes for summer use. In hot summer, ice cubes are needed to cool off the heat.

In ancient times, in the cold season, both the royal family and the people were busy collecting and storing ice, because the ice was the hardest and thickest at this time. According to Zhou Li, there was an official in charge of ice administration in ancient times, who was called "Lingren". In the cold season, Ling Ren presided over the collection of ice cubes and put them in the cellar for use in the next summer.

The Great Cold is the last of the 24 solar terms, and it is called "Great Cold" every year when the sun reaches 300 degrees on June 20-2 1 day of the Gregorian calendar. Li Sanzong's Yi was quoted as saying in Shi's General Examination: "Great cold is the middle, and the upper surface is slight cold, so it is called great cold ... extremely cold, and it is called great cold." It is said that a cold is a cold.
