Double Ninth Festival, a traditional Chinese folk festival, falls on the 9th day of the 9th lunar month every year.
The number of "Nine" is the Yang number in the Book of Changes, and the two Yang numbers of "Nine Nine" are the same, so it is called "Chongyang". Because every day and month falls on nine, it is also called "Double Nine".
In ancient times, there were folk customs such as climbing high to pray for blessings, worshipping gods and ancestors, feasting and praying for longevity on Double Ninth Festival. Heretofore, the connotation of respecting the elderly has been added.
Appreciating the autumn and being grateful for the elderly are two important themes of today's Double Ninth Festival
