As early as the Double Ninth Festival in the Warring States, there were folk customs such as offering sacrifices, climbing mountains and drinking chrysanthemum wine. The activities of the Double Ninth Festival are rich and colorful. In ancient times, there was the custom of climbing on the Double Ninth Festival, so it was also called "Climbing Festival". The climbing custom of Chongyang originated from the climate characteristics at this time and the worship of mountains by the ancients.

Climbing is also a solar term originated from nature, and climbing on the Double Ninth Festival corresponds to the spring outing of ancient people in spring and March. During the Spring and Autumn Period and the Warring States Period, the custom of "climbing to pray for blessings" was popular. There is no uniform regulation on the place of climbing, and the place of climbing is generally divided into mountain climbing, building climbing or platform climbing.

The Double Ninth Festival is the best time to enjoy autumn, and some mountain villages in the south of China still retain the characteristics of "basking in autumn". Going to the countryside to appreciate the folk customs and watch the autumn sun has become a fashion in rural tourism. "Sunbathing in autumn" is a typical agricultural custom phenomenon with strong regional characteristics.
