Knowing from a distance where a brother climbs a mountain, what festival is it when a person disappears?
It reflects the poet's feelings of missing his loved ones during the festival, and also tells us the custom of the Double Ninth Festival at that time. The Double Ninth Festival is the ninth day of the ninth lunar month, so this day is very important in the minds of the ancients. Therefore, the Double Ninth Festival is also called the Festival for the Elderly, and the ninth day is also homophonic for a long time. Therefore, people also pray for health and longevity on this day. On the Double Ninth Festival, people will climb mountains, enjoy chrysanthemums and insert dogwood into Wang Wei's poems.
Double Ninth Festival, the ninth day of the ninth lunar month, is a traditional folk festival in China. In the Book of Changes, "nine" is defined as yang number, and "nine-nine" is called "Chongyang" because of its heavy yang number. It is also called "Double Ninth Festival", because both the date and the month conform to nine. Returning to the truth of 1999, the ancients thought that 1999 Chongyang was an auspicious day. In ancient times, there were folk customs such as climbing to pray for blessings, enjoying chrysanthemums in autumn, wearing dogwood, offering sacrifices to gods and ancestors, and feasting on the Double Ninth Festival. 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.
