Dragon fur curtain
The dragon fur curtain was used during ancient times to block the hot waves in the summer, and keep interiors pleasantly cool. It was not really made of dragon fur, since there are no such creatures as dragons, so some say it was made of the skin of large boas. Surrounded by large and cold boa skins, the place would feel like an air-conditioned room. However, the skin was precious and difficult to obtain, so only the royal court was able to use it.
Bamboo lady
Ancient people in the southern parts of China preferred to use a cylinder-shaped bamboo ware, which is hollow in the middle and has grid mesh on the surface. It uses the principle of cross ventilation to cool people down, and can be hugged, or used to hold up your feet.
Fan
Last but not least, the most commonly used tool to cool down in the summer is the humble fan, and is still used nowadays. Fans were made of different materials, such as bird's feathers, bamboo, or fur.
