Historical origins of hibernation

Historically, hibernation has been called "the beginning of hibernation". The name "Keihin" is still used in Japan in the current cultural circle of Chinese characters. In the Western Han Dynasty, the Daidai Riji (Records of the Great Dai Ri) and the Xia Xiaozheng (Summer Small Positions), which were recorded during the Western Han Dynasty, it is said that the first month of the lunar year begins with the start of hibernation.

It is said to be because the sixth emperor of the Han Dynasty, Emperor Jingdi, had the name "Kai" in his name, and the word "Kai" was changed to the word "Hikikomori," which has a similar meaning, in order to avoid the taboo. After the Tang Dynasty, the word "Kai" was no longer necessary to avoid taboo, and the name "Kai Hibernation" was used again, but due to the reason of not using it habitually, the Dayan Calendar once again used the word "Hibernation", which is still in use today. The term "hibernation" is used again in the Dayan calendar, and has been used ever since.

Japan, like China, has used the term "hibernation" in its calendar. Since then, Japan has also adopted the Dayan and Seonmyeong calendars. The name "Kihikari" was first used in Japan when the calendar was changed to the Jeongheung calendar.
