The coronation ceremony is an ancient ceremony in China to show adulthood. Men are crowned around the age of 20. From this day on, the crowned man was recognized as an adult by the society. It is an ancient coming-of-age ceremony in China, Korea and Viet Nam, which evolved from the "coming-of-age ceremony" in primitive society and was held when men were 20 years old. The first of the seventeen articles in "Yili" is "crown ceremony", which shows that that era attached great importance to crown ceremony. In ancient Japan, there was a coronation ceremony imitating China, which later evolved into a ceremony of Fu Yuan. From the Nara era in Japan, ceremony means adult ceremony for men.

In the 11th year of Emperor Tianwu (683), Japan modeled on the ritual system of the Tang Dynasty, and formulated a crown-closing system. At that time, there were two kinds of crowns: lacquered yarn crown and moon crown. The coronation ceremony is also called Yan Shigu's Note: Yuan, the first also; Winner. The first book was written, so it was called Fu Yuan.

According to the Story of the Continued Day, in June of the seventh year of copper (7 14), the Crown Prince took a Canadian dollar suit, which refers to the Crown Prince, later Emperor Shengwu. During the reign of heian period (858-876) in He Qing, Fu Yuan was established as a system.

In ancient Japan, Fu Yuan's main contents include:

First, please tie up your hair. Second, by the guest crown. Due to the different status of feudal hierarchy, when adding a crown, it can be divided into two types: using a crown and using Oboshi (an ancient high hat). In peacetime, officials with more than three people and four or five people with special permission to enter the pavilion can only use the crown when adding the crown; People under six who are not qualified to go to the temple use Eboshi. With the changes of the times, in the Kamakura shogunate period (1 185- 1333), the crown was generally replaced by Eboub, so the adult human body was also called Eboub Zhu. When history entered the16th century, the coronation ceremony with Ebush was limited to the upper class and clergy, while others only shaved their foreheads and kept a hairstyle called Dai Yue (the original hairstyle for shaving their foreheads was called Dai Yue), even adults. Third, wear adult clothes. In modern times, there is also a kind of etiquette among ordinary people to congratulate adulthood with crotch cloth. When the child reaches the age of 13, the mother's relatives congratulate him with bleached cloth or red cloth.

Japan followed the old ritual system of China, and started the coronation system in the 11th year of Emperor Tianwu (AD 683). According to China's ancient theory of Yin and Yang, Jiazi and Bingyin are the most auspicious days of Guanri, especially the first month.

From 65438 to 0948, according to folk customs, the Japanese government stipulated that people over the age of 20 should live an "adult life" in order to make young people realize that they have become full members of society.
