古代还风行九九插茱萸的习俗，所以又叫做茱萸节。茱萸入药，可制酒养身祛病。插茱萸和簪菊花在唐代就已经很普遍。茱萸香味浓，有驱虫去湿、逐风邪的作用，并能消积食，治寒热。民间还认为佩带茱萸可以辟邪求吉。

Cornel, famous in Traditional Chinese Medicine (TCM), is widely planted in the north and south of China. Ancient people believed that wearing cornel twigs on the Double Ninth Festival could help prevent diseases and avoid disasters.

“遥知兄弟登高处，遍插茱萸少一人。”在吟咏重阳的众多诗词中，王维的这首七言绝句无疑是知名度极高的一首。

九月九日忆山东兄弟

(唐代 王维)

独在异乡为异客，

每逢佳节倍思亲。

遥知兄弟登高处，

遍插茱萸少一人。

Thinking of My Brothers on Mountain-Climbing Day

Alone, a lonely stranger in a foreign land,

I doubly pine for kinsfolk on a holiday.

I know my brothers would, with dogwood spray in hand,

Climb the mountain and think of me so far away.
