重阳节
重阳节，由于它是在中国农历九月初九这一天，所以又被称为重九节，至今有约两千年的历史。在中国古代，重阳节是一个重要的节日，这一天要举行各种庆祝活动，如:登高、赏菊（chrysanthemum )、插茱萸（cornel)、吃重阳糕等。登髙是重阳节的主要习俗。古人认为，在这一天登高可以避祸免灾。近年来，这个古老的节日被赋予新的含义，逐渐成为开展各种敬老活动、一年一度的“老年节”。

Chongyang Festival
Chongyang Festival，falls on the ninth day of the ninth lunar month, because of which，it is also named as the Double-ninth Festival, which has a history of some 2,000 years.
