The ninth day of the ninth lunar month is the traditional Double Ninth Festival. Because the Book of Changes compiled from ancient times to Han Dynasty (author: anonymous) defines "six" as yin number, "nine" as yang number, and on September 9, the sun and the moon are combined, and 29 is heavy, so it is called Chongyang, also known as Chongyang. The ancients thought it was an auspicious day to celebrate, and this festival was celebrated from a very young age.
Double Ninth Festival, because it is homophonic with "long-term", is the largest number in numbers, which means longevity. In addition, during the Double Ninth Festival, the autumn harvest in the north is basically over, and the cold winter is coming. When people observe the sky on the Double Ninth Festival, they often pray for good weather and good harvests in the coming year. Therefore, people have always had special feelings for this festival, and there are many excellent poems in Tang poetry and Song poetry to congratulate Chongyang and chant chrysanthemums.
