How does the Mid-Autumn Moon express Su Shi's mood?

Mid-Autumn Moon refers to the Mid-Autumn works of Yangguanqu, expressing the sadness and emotion of Su Shi and his younger brother Su Zhe who broke up soon after they got together.

Original: The clouds are full of cold, and the silver-haired people silently turn to the jade plate. If you don't meet a good night in this life, where will you see the bright moon next year?

At night, the clouds are all collected and the air is cold. The milky way is silent, and the white jade disc moves slowly in the sky. This night of my life is not always so beautiful. Where to see the bright moon next year?

This word is written from the beauty of moonlight to the joy of "full moon", from the night of that year to the Mid-Autumn Festival of the following year, and it comes down to other feelings. The image is condensed, the realm is lofty and the language is beautiful and meaningful. Yangguanqu was originally adapted from Wang Wei's poem "Send Yuan 20 An Xi", and Su Shi's ci is similar to Wang Wei's poem in four tones, which generally conforms to the lyric poetry of the poet.
