What are the artistic techniques of expressing the theme in Poem of the Moon Alone?

The whole poem writes about sadness with joy, loneliness with noise, loneliness with crowds and sadness with joy. Through imagination and anthropomorphic rhetoric, it turns the moon on the horizon and the figure under the moon, together with itself, into three people, singing and dancing, enjoying themselves on the surface, but actually lonely and desolate, expressing the author's extreme loneliness, his ambition is hard to be rewarded, and his great ambition is hard to show, and no one can match * * *

Until, holding up my cup, I asked the bright moon to bring me my shadow and let the three of us.

The background is the greenhouse, and a pot of wine in my hand can only be "I drink it alone." No one accompanied me ",so he raised his glass, invited his favorite bright moon in my life, and turned into three people with his own shadow in the moonlight, raised his glass, and the cold and cheerless scene became lively.

This sentence uses double rhetoric. Its function is to foil the poet (Li Bai)' s political incompetence but unable to get rid of his sad feeling.

Alas, the moon cannot drink water, and my shadow follows me blankly; .

But after all, the bright moon is just a bright sky, and I can't understand the poet's meaning. The shadow is just his company, which is inhuman.

The personification rhetoric is used: the moon and the shadow are both ignorant and heartless things, but the author tends to personify them, regard them as confidants and call them homophones. Compared with the mean and dirty world, it can be said that ruthlessness is better than sentience.

But for a while, I had these friends who cheered me up at the end of spring.

I use personification rhetoric. Although there is only the moon shadow, I still want to take advantage of the beautiful time of spring to eat, drink and be merry, which should reflect the poet's self-mockery of loneliness.

I sang. The moon encourages me and I dance. My shadow is rolling in the back.

The rhetorical devices of personification and antithesis were used: the drunken poet began to drink, so he sang and danced. Moonlight lingers, as if listening to good news; Silent shadows in the underground also dance with the poet.

I woke up and had sex, and then I got drunk and we lost each other.

Metaphor is personification and duality. The moon shadow wakes up and makes love until she is as drunk as a fiddler.

Will goodwill be guaranteed? I think the Milky Way is a long way.

The personification figure of speech is used: it seems that the moon and the cinema are infatuated with the poet, and they make a deep promise: "Will goodwill be safe forever?" I see the long road of the Milky Way. "
