Who wrote the "15-night Moon Appreciation Letter" to Du Langzhong?

The mid-autumn moon shines in the yard, and the ground seems as white as a layer of frost and snow. The crow in the tree stopped making noise and fell asleep. Late at night, the cold autumn dew quietly wet the osmanthus in the court. The bright moon is in the sky tonight, and people are enjoying the moon. I wonder whose home is the vast Qiu Si?

From Wang Jian, a poet in the Tang Dynasty, "Looking at the bright moon on fifteen nights to send a doctor to Du Langzhong"

Original text:

There are crows in Bai Shu and osmanthus in Coody Leng in the atrium.

I don't know who Qiu Si will meet tonight.

Creation background

This poem was written by the poet when he got together with friends in the Mid-Autumn Festival. The title of this poem is "Full Moon and Fifteen Nights, Sent to Du Langzhong", which shows that it is for Du, a good friend. The original poem says, "You must play the piano when you are young", which shows that good friends get together during the festive season instead of singing solo.

The artistic conception of this poem is beautiful. First of all, it gives people the impression of picturesque scenery. In Su Shi's words, it is "painting in poetry". There is a print with this poem as the theme in the paintings of Tang poetry in the Ming Dynasty, but this print is only the artistic conception conceived by the painter, which does not coincide with Wang Jian's original work one by one, nor does it fully show the crowning touch of the whole poem-Qiu Si.
