重阳节的命名
The Name of Double Ninth Festival
In an ancient and mysterious book Yi Jing (The Book of Changes), number "6" was thought to be of Yin character, meaning feminine or negative, while number "9" was thought to be Yang, meaning masculine or positive. So the number nine in both month and day creates "the Double Ninth Festival" or "Chongyang Festival".
因为古老的《易经》中把“六”定为阴数，把 “九”定为阳数，在农历的九月初九那天，日月并阳，两九相重，故而叫“重阳”，也叫“重九”。
