Gu Lang Yue Xing

Author: Li Bai

When I was young, I didn’t recognize the moon, so I called it a white jade plate.

I also suspected that the Yao Tai Mirror was flying in the blue clouds.

The immortal has his legs hanging down, and the osmanthus tree is not round.

The white rabbit pounded the medicine and asked who he wanted to eat with.

The toad erodes its round shadow, and the bright night is gone.

In the past, Yi fell from the Nine Crows, and heaven and man were clear and peaceful.

The Yin essence has fallen into confusion, and it is not enough to understand it.

Worry comes as no surprise, and sadness destroys the heart and liver.

Vernacular translation

When I was a child, I didn’t know the moon and called it a white jade plate.

I also suspected that it was the mirror of Yaotai Immortal that flew into the sky.

Looking at the moon at night, you can first see the feet of an immortal slowly appearing, and then a large osmanthus tree also appears.

It is said that there is a white rabbit in the middle of the moon who is pounding the elixir. Who is it pounding for?

It is also said that there is a big toad in the middle of the moon, which eclipses the moon and gradually becomes incomplete.

In the past, there was a hero named Yi. He shot down nine suns, leaving only one, so that everyone in heaven could live in peace and tranquility.

The moon has lost its brilliance due to the yin spirit’s sinking and bewitching, and it is no longer worth looking at.

I feel very worried about this, and the sadness is really heartbreaking!
