3. Special functions of pillow

In addition to providing support for head and neck during sleep to make people sleep better, pillows also serve some other functions.

Keeping cool and maintaining hairstyles:

Porcelain pillows, despite their seemingly hard and elevated structure, were ideal for staying cool and refreshed during scorching summers. Additionally, they helped people maintain their hairstyles. In ancient China, both women and men had long hair and often wore intricate headwear. By placing pillows under their necks, they could prevent their hair from getting messy and avoid frequent hairstyling.
