重阳节, Chongyang Festival, is a traditional Chinese festival that falls on the ninth day of the ninth lunar month. It is also known as Double Ninth Festival or Chrysanthemum Festival.

The festival has a long history and is said to have originated from the Han Dynasty (206 BCE-220 CE). Legend has it that a poet named Qu Yuan, who was a loyal minister of the state of Chu, drowned himself in the Miluo River on the ninth day of the ninth lunar month to protest against the corrupt government. The local people, who admired Qu Yuan, threw food into the river to feed the fish so that they wouldn't eat Qu Yuan's body. They also rowed boats on the river to search for him.

The festival is celebrated by cpmbing mountains, eating chrysanthemum cakes, and drinking chrysanthemum wine. It is also a day to honor ancestors and the elderly.

Here are some examples of how to use the term in Engpsh sentences:
