What year was Liu Yuxi's scene of appreciating Bai Juyi?

Liu Yuxi and Bai Juyi's banquet scene: In the winter of Bao Li's second year (826), Liu Yuxi and Bai Juyi met in Yangzhou. Two 54-year-old "old people" raised their glasses, and Bai Juyi knocked on the plate with chopsticks, and wrote "Lotte at the first banquet in Yangzhou" and "Drunken gift to the twenty-eight ambassadors of Liu" respectively.

"Drunk to the Twenty-Eight Ambassadors of Liu" Original: Bring me a glass of wine and play chopsticks with you. Although your poetry is first-class and can be called a national champion, it is doomed that you can't get it. Dou Rong's eyes are decent, but you stay lonely for a long time. Full officials have their own satisfactory positions, but you are empty. I also know that you should be very tired, but these 23 years have been too much loss.

This poem praises Liu Yuxi's talent, expresses extreme injustice and infinite emotion to Liu Yuxi's bumpy experience of being demoted as an official for 23 years, expresses their feelings of helping each other in the same boat, and criticizes the ruling class that does not cherish or even hurt talents. This poem embodies the characteristics of Bai Juyi's frank and sincere poetry, and dares to speak out and write all kinds of questions into the poem.

"Reward Lotte Yangzhou for the First Time" Original: Bashan Chujiang River is desolate and abandoned for 23 years. People come back. Like people in Michelle, I can only play the flute, and I am disappointed. On one side of the boat, Qian Fan races; At the head of the sick tree, every year is a spring shower. Today, listen to you sing a song, drink a glass of wine and cheer up.

First, this poem closely follows the sentence "I also know that I have lost too much in 23 years as a talent" at the end of Bai Juyi's "Drunken Gifts to Twenty-eight Generals Liu", expressing infinite bitterness and resentment at being demoted and abandoned. Then write my feelings of returning: the old friend has passed away, only endless nostalgia, and the personnel are completely different, and it feels like a lifetime ago. Infinite grief and disappointment can't help but arise. The poet then pushed aside and sank the boat, and Qian Fan entered the competition; Before a sick tree, a thousand trees strive for spring. Wash away the sad and depressed mood and show the impassioned spirit. The end of the couplet is not only a thank you for your concern, but also an encouragement to your friends, which shows the poet's firm will and optimistic spirit.
