Double Ninth Festival, the ninth day of the ninth lunar month, is a traditional festival of the Chinese nation. In the Book of Changes, "nine" is defined as yang number, and September 9 and 29 are important, so it is called "Chongyang"; It is also called "Double Ninth Festival", because both the date and the month conform to nine. In ancient times, there were folk customs such as climbing to pray for blessings, enjoying chrysanthemums in autumn, wearing dogwood, offering sacrifices to gods and ancestors, and holding birthday banquets. So far, it has added the connotation of respecting the elderly, feasting on the day of Chongyang, and being grateful for respecting the elderly. Climbing mountains and enjoying autumn and giving thanks and respecting the elderly are two important themes of today's Double Ninth Festival.
The origin of the name "Chongyang" was named after "Yang is nine" in the ancient book I Ching. In the Book of Changes, "six" is defined as yin number, "nine" is defined as yang number, and "extreme number" means that the height of the sky is "nine times". On the ninth day of September, the sun and every month meet on the ninth day, which means "the weight of 29", so it is called "double ninth". At the same time, the two yang numbers are combined, so it is called "double ninth". In the Ming Dynasty, Zhang Dai wrote "Sailing at Night": "Nine is the yang number, and its day and month coincide, so it is called" Chongyang ".
"Nine" is the Lao Yang, which is the anode number. The two anode numbers are combined, 1999 is unified, one yuan starts, and Vientiane is updated. Therefore, the ancients thought that Chongyang was an auspicious day to celebrate. In ancient times, there was a custom of drinking to pray for longevity. In the folk concept, because "nine" is the largest number, and "nine nine" and "long" are homophonic, it is endowed with the meaning of immortality, longevity, health and longevity.
According to the existing historical research, the origin of the Double Ninth Festival can be traced back to ancient times. "Lu Chunqiu Qiu Ji Ji" contains the activities of the ancients to offer sacrifices to the Heavenly Emperor and ancestors to thank them for their kindness during the harvest in September. This is the original form of the Double Ninth Festival as an autumn harvest sacrifice activity. The Double Ninth Festival began in ancient times, took shape in the Spring and Autumn Period and the Warring States Period, spread in the Western Han Dynasty and flourished after the Tang Dynasty. The name of "Double Ninth Festival" was recorded in the Three Kingdoms period. In the Wei and Jin Dynasties, the festive atmosphere became stronger and stronger, and the custom of enjoying chrysanthemums and drinking was widely sung by literati. It was listed as a national holiday in the Tang Dynasty, and it has been inherited ever since. The ancestor worship in Chongyang has lasted for thousands of years, which is an ancient folk custom with far-reaching significance. Double Ninth Festival, New Year's Eve, Tomb-Sweeping Day and Mid-Autumn Festival are also called the four traditional festivals for ancestor worship in China.
In the folk concept, "nine" is the largest number in the number, which means longevity and places people's wishes for the health and longevity of the elderly. From 65438 to 0989, the ninth day of the ninth lunar month was designated as "Respect for the Elderly", which advocated the whole society to establish the atmosphere of respecting, respecting, loving and helping the elderly. On May 20th, 2006, the Double Ninth Festival was included in the first batch of national intangible cultural heritage in the State Council.
