1. The Double Ninth Festival (also known as the Festival for the Elderly) is a traditional festival of the Han nationality, which falls on the ninth day of the ninth lunar month every year. Because the Book of Changes defines "six" as a negative number and "nine" as a positive number, on September 9, the sun and the moon merged with each other, so it is also called the Double Ninth Festival. The Double Ninth Festival was formed as early as the Warring States Period. In the Tang Dynasty, the Double Ninth Festival was officially designated as a folk festival, which has been inherited ever since. People have the custom of climbing mountains on that day, so the Double Ninth Festival is also called "Mountaineering Festival".

2. There is the custom of climbing mountains and climbing towers, and there is also the custom of eating "Chongyang cake". According to historical records, Chongyang cake is also called flower cake, chrysanthemum cake and five-color cake. There is no definite method and it is more casual.

Poetry about Chongyang;

1 "Qiu Deng Lan Shan Zhi Zhang" Tang Dynasty: Meng Haoran

Facing the white Yun Qi Fu Feifei on the mountain ridge, I can enjoy myself as a hermit.

I tried to climb the mountain and look ahead, and this mood disappeared with the departure of the swan song.

Sadness is often the mood of dusk, and the mood is often the atmosphere of autumn.

Tourists come to the village on the mountain, walk across the beach, sit at the ferry and have a rest.

The forest in the distance is like a shepherd's purse, overlooking the river bank like a crescent moon.

I hope you will pick me up, bring a basket of wine and get drunk on the Double Ninth Festival.

2. "Clear Water Camp City on Nine Days" Ming Dynasty: Qi Zhilian

Shuofang triple ninth festival, winding path is busy every year.

The sideburns are white and the chrysanthemums are still yellow.

Zhongcheng Shu has the power to save the sky, and Taizai has both merits and demerits.

Outside the cloud, the geese come from the south, and the book is reported to Jiangxiang first.
