Chinese rock pillows

Chinese rock pillows (simplified Chinese: 石头枕头; traditional Chinese: 石頭枕頭; pinyin: shítou zhěntou) played an important role in ancient China. Made from jade, they were believed to translate the energy from the stone to the human brain. Originating in the Ming dynasty, this piece of material was trusted to cure headaches or depression, or simply to better the intelligence of those who use it. It was more common among royalty because it was expensive and rare. Families often married off children based on the quality and intricacy of these pillows. Today, rock pillows are still commonly used during the hot summer months in China.
