Here’s The Moon in a Well (詠井中月) poem in its entirety, with Hangul equivalent.
English translation of The Moon in a Well (詠井中月) by JeoYong Noh:
An acolyte craving the moonlight in a well
Draws water with it into a carafe.
Yet back to the temple, he should see,
Tilting the jar, the moon be gone as well.
The poem basically portrays the desire of human being which is illusory.
