What does Li Bai's ancient poem "Drinking the Moon Alone" mean?

Flowers in the next pot of wine, no friends, drink alone. Raise my cup, I invite the bright moon, which brings me its shadow and makes us three people. The moon doesn't know how to drink, but the shadow in front of it is behind. I have to mingle with them and enjoy the happiness of spring. I'm Song Yuepei, and I dance. My shadow is rolling in the back. Wake up and be happy together, and disperse after drunkenness. I am willing to stay with them forever and forget the harm of friendship, just like the Milky Way.

Put a pot of wine in the flowers, pour it for yourself, without friends and relatives.

I have to raise my cup to invite the bright moon in the sky. As a result, the bright moon, the shadow under the moon and I seem to be three people.

However, the moon doesn't know the taste of drinking, and the shadow can only follow me in vain.

Nevertheless, I regard the moon and shadow as my companions for the time being, because how could I miss this pure night?

I sing loudly, and the bright moon is like a fleeting time; I danced to my heart's content, and my shadow was broken and messed up.

I was very happy with them when I was awake, and separated after I slept.

From now on, I would like to make an unforgettable friendship with Yue Ming and meet to travel to the remote fairyland in Han Yun.

Enjoy the moon and drink four poems alone. This is the first poem, which expresses the anguish of a bosom friend. The poem begins with a description of loneliness. Loneliness is to write quietly, but also to compare silence with sadness. In the contrast of colors, it expresses the deep lament that although there are beautiful scenery, bosom friends are hard to find. The concept of "raising a glass" is ingenious. When no one is talking, the moon and the shadow are friends. However, the moon doesn't know how to drink, and the shadow is accompanied in vain, which deepens its loneliness. In order to eat, drink and be merry in time, the poet opened his mind and danced lightly. The moon lingers because of listening, the shadow is messy because of dancing, and it seems to be lonely and quietly passed away. However, the poet is miserable to the extreme. The moon will not be perfect, and the "chaotic shadow" is a wonderful portrayal of inner chaos. What is even more embarrassing is that when you are awake, there is a bright moon to make love, and when you are drunk, you will be scattered. Therefore, the word "temporary companion" is the illusory sustenance of the author's feelings. The last two sentences reflect the poet's romantic poetic style and find some spiritual comfort in completely denying the dark reality.
