The harvesting and storage of ice are recorded in a poem of circa 1100 B.C. in the Shih Ching, the famous collection of Food Canons. There is also mention of a festival held when the ice houses were opened for summer use: "In the days of the second month, they hew out the ice. . . in the third month they convey it to the ice houses which they open in those of the fourth, early in the morning, having offered in sacrifice a lamb with scallions."
Confucius, author of Shih Ching
