How did the ancients live in such hot weather?

How did the ancients spend this moment in such hot weather? Ten thousand air conditioners in Qian Qian are working hard, bringing us rare coolness. It is hard to imagine how ancient people lived before the invention of air conditioning. In fact, in the long history without air conditioning, the wisdom of the ancients in cooling off summer heat should not be underestimated. In summer, the Roman emperor Eraga Burroughs got a lot of snow from the mountains, and then built a snow-capped mountain in the garden next to his home. The Romans really love to toss about in this respect. They used to use a water pipe system to bring cold water from mountainous areas to densely populated urban areas. These pipes are installed in the walls of the house, which further reduces the indoor temperature when cooling the walls. These arched towers used to draw water can still be seen all over Europe today. At the same time, as long as the temperature rises, the Romans like to take a bath, and the local tyrants will let slaves fan themselves with fans made of ostrich hair all day. At this point, the social enjoyment of the Romans is almost the same as that of China. Skillful craftsmen in Han Dynasty developed a kind of large-scale cooling appliance with "impeller fan wind", and its cooling effect was very impressive. According to "Miscellanies of Xijing", seven paddles were installed on the ship, one person shook the handle, and the seven impellers spun rapidly, stirring the air to produce a cool breeze. Of course, this kind of large-scale equipment is also unaffordable for ordinary people, and only the royal nobility can enjoy it. In the Tang Dynasty, Emperor Xuanzong, who knew how to play, built a "pavilion" for himself. There is a big windmill outside the Liang Dian, which is driven by the water in the palace canal and lifts the water to the roof. There is a sink on the roof. When the water is full, the sink on the roof will be opened by a mechanism, and the water will slowly flow down the eaves, which is a living man-made "water curtain hole". Not only is it extremely cool, but you can also sit indoors and enjoy the scenery. At the same time, the water vapor brought by the rotation of the windmill is moist, providing natural wind, full of fun and pure natural flavor.
