Double Ninth Festival
The origin of the name "Chongyang" was named after "Yang is nine" in the ancient book I Ching. In the Book of Changes, "six" is defined as yin number, "nine" is defined as yang number, and "extreme number" means that the height of the sky is "nine times". "Nine" is the Lao Yang, which is the anode number. The two anode numbers are combined, 1999 is unified, one yuan starts, and Vientiane is updated.
Therefore, the ancients thought that Chongyang was an auspicious day to celebrate. In ancient times, there was a custom of drinking to pray for longevity. On the ninth day of September, the sun and every month meet on the ninth day, which means "the weight of 29", so it is called "double ninth". At the same time, the two yang numbers are combined, so it is called "double ninth". In the Ming Dynasty, Zhang Dai wrote "Sailing at Night": "Nine is the yang number, and its day and month coincide, so it is called Chongyang".
The creative background of "I miss my Shandong brother on vacation in the mountains"
This poem was written by Wang Wei when he was seventeen. It was written because he missed his relatives in his hometown on the Double Ninth Festival. Wang Wei wandered between Luoyang and Chang 'an alone. September 9th is the Double Ninth Festival, and some places in China have the custom of climbing mountains. The thirty-second volume of "Taiping Magnolia" quoted the story of local customs: "This day is established by convention and matured with the strong spirit of Cornus officinalis. On this day, the folded house is blocked to prevent early cold. "
