First, store ice cubes in winter.
When it freezes in winter, the ice will be cut off and stored in the cellar. The underground temperature is relatively low. If the seal is good enough, no air will enter, and ice cubes can be stored in the cellar for a very long time. In summer, ice cubes are dug out of the cellar and placed in every corner of the palace.
Yang Guifei's bedroom is cooled with ice cubes, and the temperature of the whole palace will drop. Besides, there are always maids waiting for the fan, just like an artificial electric fan, so you won't feel very hot in your bedroom.
Second, eat cold drinks.
Don't think that cold drinks are the welfare of our modern talents. In fact, the ancients have already studied it. In summer, the large ice cubes in the cellar are used to cool the house, and the small ice cubes can be used to make shaved ice or cold drinks.
Mash the ice cubes and add fresh fruit to make a bowl of simple fruit shaved ice. Some concubines don't like ice. You can put the prepared soup in the ice and take it out to drink. Drink a bowl when the weather is hot, and it will get cold at once. It is said that Yang Guifei is particularly afraid of heat because of her plump figure. She must drink cold drinks every day, or she will lose her temper.
Third, take a bath.
When the weather is hot, bathing is the most comfortable. In the past, concubines were only bathed in their own bedrooms, and only the emperor was entitled to enjoy the special Tang Chi. But Yang Guifei is the emperor's favorite concubine, so she has the right to take a bath.
When taking a bath, a plate is served by the maid, and water can be added at any time, as well as wine and food, which is very comfortable. These are the privileges enjoyed by Yang Guifei, and other concubines do not have such treatment. It is a great honor to enjoy the right to take a bath once a year.
