We dislike too hot days. Luckily, we have air conditioners and fridges. How did Chinese people stay cool in the hot season before they have air conditioners and fridges?

The most common way Chinese people in the past kept cool was to use fans. Many fans had poems or drawings on them.

 Beginning in the Sui dynasty(朝代), Chinese people started to use porcelain pillows(瓷枕). These pillows felt cool, so people could sleep well on them.

People in old times didn't have fridges to make ice.  Instead, they collected ice in winter and kept it underground, sometimes in wells(井). When summer came, they got the ice out and put it in their living rooms to cool them down.

Rich people and members of the king family had more expensive ways to keep cool. As early as the Han dynasty, some people used a tool(工具) like modern electrical fans. It was made of a wheel(轮子) and some fan blades(叶片). A person would pull a rope to make the wheel spin(转) and then the blades would spin around fast.

In the Tang dynasty, people found a way to make their whole house cool. They built their houses next to the water, used some machines to carry water to the top of the house, and made it flow down from the eaves(屋檐). This man-made waterfall brought cool air into the house.
