1, flower cake. Respect the elderly on the Double Ninth Festival and climb high to avoid disasters. "Gao" and "Gao" are homophonic, and they also mean "step by step" and "long life", so "Chongyang Flower Cake" has become a popular holiday food. Eating flower cakes in Chongyang began in the Western Han Dynasty, when it was called "Peng Bait", that is, millet cakes. In the Song Dynasty, it was very popular to eat flower cakes on the Double Ninth Festival, which has been passed down to this day. The reason for eating flower cakes on Double Ninth Festival is the climbing custom of Double Ninth Festival. Where there are mountains, we can climb them, but where there are no mountains, we will try to make up for them and replace them. Because "cake" and "high" are homophonic, the custom of eating flower cakes has emerged.
