Ancient people’s methods of summer heat;

In our impression, when the ancient emperors were in office, there were often two maids with long-handled palace fans behind them. The two crosses, showing the emperor s distinguished beauty. In fact, the first summer work of the two palace ladies was to use a fan to chase mosquitoes and flies that harassed the emperor into the palace, while fanning the air to make the emperor feel cooler.

It is obviously not the best way to use a fan to cope with the high temperature. Therefore, in the summer, the emperor often chooses to build a palace in a place with mountains and rivers and clear air to avoid the summer heat.

As early as in the Spring and Autumn Period and the Warring States Period, there was a Wang Goujian who traveled in the summer, and lived in an ice cook, which is larger than a sedan. In the Tang and Song dynasties, there was a cold hall. The so-called cold hall was to generate wind by rotating the fan to direct the cold air on the cold water to the indoor air. Another method is to direct the cold water to the roof and pour down the eaves. A huge man-made waterfall is formed around, so that cold air permeates the water curtain, so as to reduce the room temperature.

Compared to this method, taking ice to cool down seems cheaper, so it has been widely used by the imperial palaces of all ages. Ancient palace staff would cut out ice cubes in the rivers in winter and retrieve them and hide them in huge cellars. Take it out in the summer and put it around the main hall. As the ice cubes melt little by little, the temperature in the room gradually decreases. It feels better to live in such a noiseless air conditioner.

Xia Xingbing is like gold. For most ordinary people in ancient times, it could only be a cold imagination. A poet from the Tang Dynasty, Du Fu, said: The midsummer has a short night, and the openness is slightly cool. The common people can only hope that the night comes early, turn off the candles, open the doors and windows, and give the switch of air conditioning to the master Already.
