The ninth day of the ninth month of the Chinese lunar calendar is a traditional Chinese festival, the Double Ninth Festival, which falls on Oct 17 this year.

In Chinese culture, nine has long been regarded as the number of yang, making the day of the festival one of two yang numbers, while “chong� in Chinese means double - thus creating the name of the festival, Chongyang.

Traditional customs of the festival include reaching a mountain peak, wearing dogwood, eating double ninth cake and enjoying chrysanthemum.
