Double Ninth Festival

The 9th day of the 9th lunar month is the traditional Chongyang Festival, or Double Ninth Festival. It usually falls in October in the Gregorian calendar. In an ancient and mysterious book Yi Jing, or The Book of Changes, number "6" was thought to be of Yin character, meaning feminine or negative, while number "9" was thought to be Yang, meaning masculine or positive. So the number nine in both month and day create the Double Ninth Festival, or Chongyang Festival. Chong in Chinese means "double." Also, as double ninth was pronounced the same as the word to signify "forever", both are "Jiu Jiu," the Chinese ancestors considered it an auspicious day worth celebration. That's why ancient Chinese began to celebrate this festival long time ago.

The custom of ascending a height to avoid epidemics was passed down from long time ago. Therefore, the Double Ninth Festival is also called "Height Ascending Festival". The height people will reach is usually a mountain or a tower. Ancient literary figures have left many poems depicting the activity. Even today, people still swarm to famous or little known mountains on this day.

On this day, people will eat Double Ninth Gao (or Cake). In Chinese, gao (cake) has the same pronunciation with gao (height). People do so just to hope progress in everything they are engaged in. There is no fixed ways for the Double Ninth Cake, but super cakes will have as many as nine layers, looking like a tower.

The Double Ninth Festival is also a time when chrysanthemum blooms. China boasts diversified species of chrysanthemum and people have loved them since ancient times. So enjoying the flourishing chrysanthemum also becomes a key activity on this festival. Also, people will drink chrysanthemum wine. Women used to stick such a flower into their hair or hang its branches on windows or doors to avoid evilness.

In 1989, the Chinese government decided the Double Ninth Festival as Seniors' Day. Since then, all government units, organizations and streets communities will organize an autumn trip each year for those who have retired from their posts. At the waterside or on the mountains, the seniors will find themselves merged into nature. Younger generations will bring elder ones to suburban areas or send gifts to them on this day.

农历九月九日，为传统的重阳节。因为古老的《易经》中把“六”定为阴数，把“九”定为阳数，九月九日，日月并阳，两九相重，故而叫重阳，也叫重九，古人认为是个值得庆贺的吉利日子，并且从很早就开始过此节日。

在古代，民间在重阳有登高的风俗，故重阳节又叫“登高节”。相传此风俗始于东汉。唐代文人所写的登高诗很多，大多是写重阳节的习俗;杜甫的七律《登高》，就是写重阳登高的名篇。登高所到之处，没有划一的规定，一般是登高山、登高塔。
