Poetry for Marrying a Girl. It was written by a poet who cultivated immortality in the Tang Dynasty. I need a detailed explanation. Can some kindhearted person help me?

The general idea: I advise you to have a glass of wine and compose a poem for your sorrow. Ever since I frequently saw the court changing its owners (referring to the rise of vassal towns in the late Tang Dynasty and the changes in government orders every day), I have long lost the joy that I had when I was in Yaochi Fairyland (these words are to persuade my daughter, because in the past, girls had to make a certain decision when they got married. I cried and cried in sadness to show that I couldn't bear to leave my parents, so the old man said that I no longer have joy. Without joy, there is no sadness. I have no emotions anymore, so you don't have to look sad anymore). I’ll bring you a glass of wine. Don’t blame the world where people are striving for fame and fortune for being different from heaven. If you had known earlier that it would be better to be in the fairyland than in the human world, then you would not have to regret riding a horse from the Yaochi to the human world in a hurry. Now that you are riding a carriage drawn by eight horses on the long road of life, are you still thinking about the past when you stayed with the Queen Mother in Emperor Mu's Zhao Palace? The rule means to persuade a daughter to get married. Because the literal translation is rather cumbersome, I only translated the general meaning, the same below). I think back then you held a banquet in the Yellow Emperor's beautiful garden Xuanpu, with Juntian Guangle (the name of fairy music) echoing all around. You sisters kept feasting until the stars were setting, the dew condensed on the grass, and the Jade Rabbit returned to the west, covered with the setting sun. The wine glass in the sunset was reflected red by the morning sun again (how happy I was then). But now when I look back and look to the west, I don't know where Kunlun is. Instead, I feel that it was a hallucination when I was drunk or a scene in my sleep. These are all because you heard someone playing the sheng and singing near the Yaochi and stopped returning to the Yaochi (that's why you were punished by the Queen Mother). You must know that the six thousand years in the world are just the time to drink a glass of wine in the sky, and the moon and stars in the sky are bright all night long, and the strange flowers and trees are spring all year round. Now you already know how misleading those popular poems such as "The blue sea and blue sky are in my heart every night" are. Look, when the autumn wind blows and the dew is strong, there are only a few sealed trees on the tomb of Emperor Wu of the Han Dynasty swaying in the cold wind. (And no one remembers the touching story of Emperor Wu of Han Dynasty and Mrs. Li). Emperor Ming of the Tang Dynasty did not get the help of the Queen Mother's fairy peach, so he fell from the sky to Longxi like floating dust (the emperor of the Tang Dynasty was originally from Longxi). Although he had achieved peace in the world for more than 50 years, he could only become immortal after getting close to the practice of immortality and alchemy. Gained immortality. If they only need the support of the Queen Mother's Immortal Power, please look at the people at the top of the list of immortals (meaning that personal cultivation is more important). But now the cold moon is shining on Lishan Mountain, and even the dewy autumn flowers seem to be crying, as if they are mourning that the late emperor ascended to heaven early. There are still deer that were kept in captivity back then. They still surround the hot spring where the imperial concubine bathed from time to time, waiting for the arrival of the green feather canopy of Emperor Ming and the imperial concubine. But the smoke and dust of Youji (referring to the Anshi Rebellion) rushed into the sky, and the sound of bells and drums in the hot spring palace prepared for Concubine Yang's bath also stopped. In the middle of the night, the guards did not even have time to prepare the ceremonial guard, and Emperor Ming's chariot set off in a hurry. There are still gold and jade jewelry belonging to Concubine Yang in the dressing box. No one in the hot spring seems to be still taking a bath, but the thorns on the tomb have blocked their path to heaven and immortality, and only the sad evening breeze is blowing on their tomb. The pine tree above (this long paragraph is to advise his daughter not to forget to practice spiritual practice after marriage, and uses the contrast between heaven and earth as a metaphor with the love stories of Emperor Wu of the Han Dynasty and Mrs. Li, Emperor Ming of the Tang Dynasty and Concubine Yang. The old immortal imagined his daughter as The jade girl next to the Queen Mother, who also received the fairy peach as a reward from the Queen Mother, has higher qualifications to become an immortal than Emperor Ming of the Tang Dynasty. However, to become an immortal, you must not only rely on qualifications, but also rely on spontaneous cultivation. Otherwise, like Mrs. Li and Yang Guifei, Even if he becomes a fairy, he will still be ranked very low. Next, he will praise his daughter and son-in-law). You are the goddess in the sky, and he is the jade man of the immortal capital. The joy of your union will be tonight, and tonight you will have the harmony of the phoenix and the phoenix. The luan and the phoenix sing in harmony, flying together, and their life span is as long as the sky, and their happiness and longevity are boundless. You have a body made of jade, an appearance made of flowers, your temples are as fluttering as cicada wings, your hair is as black and clean as dark clouds, your face is white without powder, and your lips are red without grease. Your beauty has already surpassed the legend. fairy. Tonight you are going to practice together under the gorgeous curtain next to the silver candlestick. The breeze shakes your pearls and jade jewelry, and the crisp sound reaches to the sky. Don't just remember to dress up to please your husband, you should work together to become immortals together as soon as possible. Now the three stars (morning stars) in the Milky Way have faded away, and soon the world will usher in the first ray of dawn from the east. Men and women should also practice together at night, and you should not let people sleep alone (it is considered that the daughter is not happy with this marriage, so the old man is so long-winded).
