So far, it has added the connotation of respecting the elderly, feasting on the day of Chongyang, and being grateful for respecting the elderly. Climbing mountains and enjoying autumn and giving thanks and respecting the elderly are two important themes of today's Double Ninth Festival.
The Double Ninth Festival originated from the worship of astronomical phenomena, which began in ancient times, spread in the Western Han Dynasty and flourished after the Tang Dynasty. According to the existing historical data and textual research, in ancient times, there were activities of offering sacrifices to heaven and ancestors in the autumn and the season; The ancients offered sacrifices to the Emperor and ancestors when the crops were harvested in September, which was an activity to thank the Emperor and ancestors for their kindness. This is the original form of the Double Ninth Festival as an autumn harvest sacrifice activity.
The Tang Dynasty is an important period when traditional festival customs are mixed and shaped, and its main part has been passed down to this day. Chongyang ancestor worship has lasted for thousands of years and is an ancient folk custom with far-reaching significance. Double Ninth Festival, New Year's Eve, Tomb-Sweeping Day and July 30th are also called the four traditional ancestral festivals in China.
