良月才经四日，
The beautiful moon has just passed four days,

彭城庆诞真贤。
Celebrating the birth of a truly virtuous person in Pengcheng.

从来斗酒百诗篇，
Throughout history, there have been countless poems composed over wine,

锦绣文章灿烂。
Brilliant and splendid literary works.

自合宰官身现，
He himself has become an official,

谁知富贵由天。
Who knows that wealth and honor are bestowed by the heavens.

但教福寿喜双全，
May he be blessed with both longevity and happiness,

直看子孙荣显。
And may his descendants prosper and flourish.
