Double Ninth Festival, the ninth day of the ninth lunar month, is called "Double Ninth Festival". People have the custom of climbing mountains on that day, so the Double Ninth Festival is also called "Mountaineering Festival". There are also sayings such as Double Ninth Festival, Cornus officinalis and Chrysanthemum Festival. Because the homonym of "99" on the ninth day of September is "long" and has a long-term meaning, activities to worship ancestors and respect the elderly are often carried out on this day. The law also clearly stipulates that the ninth day of the ninth lunar month is the festival for the elderly every year.
