Background

The Double Ninth Festival is a traditional Chinese holiday observed on the ninth day of the ninth month in the Chinese calendar. According to Wu Jun, it dates back to the Eastern Han dynasty (25–220 AD).

According to the I Ching, nine is a yang number; the ninth day of the ninth month in the Chinese calendar (or double nine) has extra yang (a traditional Chinese spiritual concept) and is thus an auspicious date. Hence, the day is also called "Double Yang Festival". It is customary to climb a mountain, drink chrysanthemum liquor, and wear the zhuyu plant. Both chrysanthemum and zhuyu are considered to have cleansing qualities and are used on other occasions to air out houses and cure illnesses.

On this holiday, some Chinese also visit the graves of their ancestors to pay their respects.
