On the ninth day of the ninth lunar month, comes the traditional Chinese holiday: the Double Ninth Festival. The number nine in both the month and the day creates the double nine. The Festival is also called "the Height Ascending Festival" because of the custom of climbing a high mountain.

Apart from expelling bad luck and disasters, climbing mounting also indicates “climbing to a higher position”, and it is also an important reason why ancient people pay much attention to this custom.

Another reason that climbing mountains are valued by people, especially by the elderly is that it has a meaning of “climb to a longevous life”. Also, for this reason, people believe that climbing mountains can make people live a more longevous life.

In 1989, the Chinese government decided the Double Ninth Festival as Seniors' Day. The traditional culture of Double Ninth and that of the modern were finely combined. It becomes a festival of respecting for the old people, and loving, helping the old.

Below a famous Chinese Poem for your reference:

《Double Ninth, Missing My Shandong Brothers》

Wang Wei

As a lonely stranger in the strange land,

Every holiday the homesickness amplifies.

Knowing that my brothers have reached the peak,

All but one is present at the planting of flowers.
