In ancient times, summer was very hot. As the weather is very hot, how should emperors and concubines relieve the heat?

Barefoot, wearing thin gauze, sitting on a straw mat.

In summer, the windows of various palaces can be erected, and the windows at the bottom can be removed for ventilation. Hanging curtains on the eaves can not only block the direct sunlight, but also ventilate.

The emperor received the minister and entertained himself by drinking green tea, scented tea or milk tea. This bowl of fragrant tea can both refresh and relieve summer heat.

There was an ice room in the palace of the Qing Dynasty. According to the Story of the Qing Palace, "In the Forbidden City, there are five ancient ice chambers, four of which have 5000 pieces of ice each, and the other has 9226 pieces of ice." These ice chambers are buried in the ground 1.5m, with a pit width of 6.36m, a length of 1 1.03m and a volume of over 330m2. The ground is covered with stones, which store more ice cubes. They are fished out of the Royal River in the cold winter of March 9 every year, cut into ice cubes according to a certain size, and stored in the freezer for summer use. The buildings in the Forbidden City are tall, deep and spacious, and the scorching sun can't reach half of the ground inside. In addition, the roof of the temple is very thick, and there is a layer of iron quilt, which can't be penetrated by the hot sun. So this ice cube has two purposes: one is to put it in the palace, and the water absorbs the heat in the room, thus reducing the indoor temperature; In the poem "Ten Chants of Summer" by Emperor Qianlong, there is a description of placing ice cubes indoors; "Guangsha has no heat, and it stores broken ice in a small plate; It's cooler than a chest fan, and the color is like a jade pot. " First, it is used to cool food and make it into cold drinks. Wang Zeng, a poet in Qing Dynasty, once wrote a poem praising: "The cherry loses its fragrance after tea, and the copper bowl calls for selling ice." The most famous of these practices is the "iced sour plum soup" in old Beijing. Herbal tea of later generations has the effects of clearing away heat, relieving summer heat, promoting fluid production to quench thirst, invigorating spleen and appetizing.
