去年称寿处，北斗天浆，今夜天浆挹南斗。

《洞仙歌》

千崖滴翠。正秋高时候。
Thousands of cliffs drip with emerald green. It is the height of autumn.

橙黄橘绿又重九。有蓬壶仙子、赤鲤来游，
Orange and yellow, green and vibrant on the Double Ninth Festival. The Immortal of the Reed Hut and the Red Carp come to play.

风云会，施展经纶妙手。去年称寿处，北斗天浆，
The meeting of wind and clouds, the display of extraordinary skills. At the place where we celebrated last year, the celestial nectar of the Big Dipper,

今夜天浆挹南斗。听笙箫云里奏，
Tonight the celestial nectar is poured from the Southern Dipper. Listen to the melodies of the sheng and xiao playing in the clouds,

月满琼楼，瑶台上、拥出嫦娥观酒。
The moon is full, illuminating the beautiful towers, and on the jade stage, Chang'e comes out to watch the wine.

待脚踏层云倒天河，尽倾向霞觞，与君为寿。
Waiting to tread on the layers of clouds and pour the wine into the Milky Way, celebrating a long life together.
