The Chong Yang Festival, also known as the double Ninth Festival, falls on October 25th in the Gregorian calendar this year. It is a traditional Chinese holiday and is observed on the ninth day of the ninth month in the Chinese lunar calendar.
According to the Yi Jing (I Ching), or The Book of Changes,
the number "6" was thought to be a Yin character, meaning feminine or negative, while the number "9" was thought to be Yang, meaning masculine or positive.
Therefore, the double ninth is called Chong Yang. Chong (Chinese character 重) means "double." The pronunciation of the number "9" is the same as the pronunciation of the Chinese character "久", which symbolises "forever". Double ninth (the ninth day of the ninth month) is pronounced the same as "久久". Hence, the number nine in both month and day creates the Double Ninth Festival. Chinese ancestors considered the festival an auspicious day worth celebration.
It is customary to climb mountains, drink chrysanthemum liquor, and wear the zhuyu (茱萸) plant (Cornus Officinalis) to celebrate the festival. People consider both chrysanthemum and zhuyu to have cleansing qualities and use them on other occasions to air out houses and cure illnesses.
