Liu Yuxi was very moved after hearing this, and made an impromptu reply to Bai Juyi's song "Yangzhou will enjoy Lotte for the first time":
The mountains were desolate and silent for twenty-three 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.
Qian Fan crossed the ship's rail; Ten thousand saplings grow on the dead trees. )
Liu Yuxi took Bai Juyi's words, outlined his experience of defending Bachu and surviving the robbery, and focused on expressing his feelings in this specific environment. Twenty-three years of relegation, although the process is long and bumpy, can not make us depressed. "By the sinking ship, Qian Fan passed by, and in front of the diseased tree, it was Wan Muchun." The sunken ship and the diseased tree were indeed melancholy, but Qian Fan passed by the sunken ship, and there was a spring struggle in front of the diseased tree. He encouraged Bai Juyi not to grieve for his loneliness and idleness, not to suffer for the ups and downs of officials, and to face the changes of the world with an open mind.
In the fifth year of Daiwa (83 1), Yuan Zhen, Bai Juyi's best friend, died of illness, and Liu Yuxi quickly filled the vacancy in Bai Juyi's heart, thus giving birth to the famous "Bai Liu" group. In October of this year, Liu Yuxi was transferred to Suzhou Secretariat, passed by Luoyang on the way to his post, lived in Bai Juyi's home in Daoli, sang songs at night, and talked about poetry and paper. 15 days later, the two were still inseparable, and Bai Juyi braved the heavy snow to bid farewell to Liu Yuxi. After Liu Yuxi took office in Suzhou, knowing that Bai Juyi liked cranes, he tried his best to get a Huating crane and entrusted it to Bai Juyi. Bai Juyi was very happy and wrote a poem thanking him, saying that this Huating crane was "a precious treasure".
In the first year of Kaicheng (836), Liu Yuxi went to Luoyang and Tongzhou as a secretariat, sharing the capital with the princes and guests. Bai Juyi lives in the road and Liu Yuxi lives in Jixian Lane. They "gather virtuous and diligent on the street" and "make more blind dates", which makes it more convenient to meet and sing more frequently. Bai Juyi compiled their poems into a book, and also published a special book, Bai Liu Chorus, which was the best seller of that year.
