There is a saying in Bai Juyi's poems that "the scenery is long and lonely, and the official position of the Manchu Dynasty is abolished". He believes that most of his peers have been promoted, and only Liu Yuxi has wasted his time in a bleak state. Obviously, he is unfair to Liu Yuxi, as he said in his poem: "I also know that the name of the couplet will be folded, and most of it will be folded in 23 years." What does rachel think of this? He went and wrote optimistically in the poem appreciation: "Qian Fan is on the side of the sunken ship, and Wan Muchun is in front of the sick tree." "Shipwreck" and "sick tree" are two images summarized in his life, but there is no resentment in his poems. It is to comfort Bai Juyi not to care about his life frustration and career frustration, which is manifested as an open-minded and cheerful attitude towards world changes and career promotion. As he said in his poem, on the bank of the shipwreck, Qian Fan competed; Before the sick tree, thousands of trees sprout in spring. After living in exile for more than 20 years, he didn't feel depressed or hurt. That's because he has experienced the honor and disgrace of the world and witnessed the ups and downs of other people's careers.
