Flower cakes are eaten as the staple food in the Double Ninth Festival, which respects the elderly and climbs mountains to avoid disasters. The word "cake" is homophonic with "height" and has the meaning of "rising step by step" and "longevity and longevity", so "Double Ninth Flower Cake" has become a popular holiday food.

In the crisp autumn, I bid farewell to my youth, taste flower cakes, admire chrysanthemums and recite Tao Yuanming's poems, and hold various activities to respect the elderly, which is full of human affection. In southern China, there is a custom of inserting dogwoods on the Double Ninth Festival to exorcise evil spirits, while in Beijing, respect for the elderly is the main content, so there are many chrysanthemums, but few people insert dogwoods.
