The whole poem takes the Mid-Autumn Festival as the main content, depicting the Mid-Autumn Festival poet enjoying the moon alone in the atrium. The moonlight covered the ground of the yard with a layer of white, and birds perched on the trees. The cold autumn dew quietly wet the osmanthus in the yard. People are looking up at the bright moon tonight. I wonder who is pregnant with Qiu Si at this time. From the desolate and lonely scene around him, the poet leads a person to ponder deeply in the distance, thus expressing the poet's homesickness and sadness in the Mid-Autumn Festival.
