The Book of Songs, the national wind, the wind, ............................................................................................................................................................. cut ice on the second day in July, and Lingyin was satisfied on the third day. On the fourth day, its flea sacrificed the lamb to the leek. .........., therefore, used to collect and store ice for the summer is much earlier than during the Warring States Period, because The Book of Songs is a collation of past data by Confucius, which is very popular, otherwise it will not be circulated in the Book of Songs. This method was popular until the late Qing Dynasty.

With the development of productivity and the progress of science and technology, machinery is gradually used. It was most popular in the Tang and Song Dynasties.

In the Tang Dynasty, the emperor built a cool hall for summer in the palace, in which mechanical transmission refrigeration equipment was installed. This kind of equipment adopts the way of cold water circulation, which is shaken by a fan wheel to generate wind power and deliver cold air to the temple. At the same time, cold water is sent to the roof by machinery, so that it can go straight down the eaves, forming an artificial water curtain to arouse the chill, thus achieving the purpose of cooling off the heat. In the Song Dynasty, the design was more exquisite and luxurious.

In addition, Song people also had the custom of enjoying the cool in pavilions and flooding lakes for summer.

However, harvesting and storing ice is still very popular and expensive, which is not available to extremely expensive people. It is extremely rare in history that Yang, a famous minister in the Tang Dynasty, built an iceberg for the summer. In the book "The Legacy of Kaiyuan Tianbao", it is recorded that everywhere Yang's son and brother go, they have to take big ice cubes for craftsmen to chisel into mountains, surrounded by banquets. Although the guests are full of wine, they have their own cool colors. "Yunxian Miscellaneous Notes" said: "Chang 'an ice and snow, midsummer, the price is equal to the golden wall. "
