In ancient China, pillows were made from different materials. They took wood, bamboo and even jade, bronze and porcelain.

It was believed that a jade pillow makes a person smarter. Hard pillows were preferred precisely because of this belief. Although the Chinese knew how to make soft pillows, it was believed that they, on the contrary, steal energy while a person is sleeping.

On a picture you can see a Jin Dynasty ceramic pillow, beautiful but obviously uncomfortable.
