As the old saying goes, what are the names of pillows? (Please indicate the dynasty or time)
Sima Guang, a famous historian in the Northern Song Dynasty, used a small log as a pillow. When he slept, he just moved his head and fell off the pillow. He woke up immediately. After waking up, he continued to study hard. He named this pillow "police pillow". In order to strengthen the body during sleep and achieve the purpose of treating diseases, the ancients also put medicines in pillows to treat diseases, which are called "medicine pillows". Li Shizhen's Compendium of Materia Medica said: "Tartary buckwheat skin, black bean skin, mung bean skin, cassia seed ... make pillows until they are old and bright." There are all kinds of pillows among the people, most of which aim at "clearing fire" and "removing heat". Now pillows are more and more widely used in medical care, such as "magnetic therapy pillow", which has certain curative effect on neurasthenia, insomnia, headache and tinnitus. A kind of "cervical pillow" is very popular in America and Hong Kong. Sleeping on this pillow can completely relax the muscles of the neck, shoulders and skull base and eliminate the fatigue of the day. At present, Japan has also developed a "fitness pillow", which can continuously release energy like an oscillator, promote human blood circulation and metabolism, and play a hypnotic role, so as to better play its role as a sleep tool. In recent years, pillow enterprises in Qingdao have launched the business of measuring pillows and setting pillows, providing customers with personalized and professional services of "measuring pillows and setting pillows" for five minutes. Because everyone's neck radian and height are different, it may be the best choice to tailor a healthy pillow with different radians.
