Liu Yuxi, a native of Pengcheng (now Xuzhou, Jiangsu) in the Tang Dynasty, was a distinguished guest of the Prince, who was known as Liu Bin. And Liu Zongyuan are also called "Liu Liu". He lived in Luoyang in his later years and sang with Bai Juyi, so he was called "Bai Liu". In the ninth year of Zhenyuan, he was promoted to the first place in imperial academy, entered the course of erudition and macro-speech, engaged in the Huainan shogunate, and served as the censor. Wang brought the used things into the forbidden area, discussed them with him, and said everything. Transfer it to Yuan Wailang and sentence him to a salt and iron case. Uncle Wen was defeated and demoted to the secretariat of Langzhou. During his relegation, he met Bai Juyi in Yangzhou. Bai Juyi wrote "Drunken Gifts to Twenty-eight Ambassadors of Liu", and Liu Yuxi thanked Bai Juyi for "rewarding Lotte in Yangzhou for the first time" and later demoted Sima Langzhou. When you are down and out, you don't talk to yourself, but you spit and satirize the distance. Quite vulgar and good at witchcraft, according to the poet's intention to taste. Relying on his voice, he wrote more than ten poems on bamboo branches and sang them in Wuling Creek Cave. Live for ten years, call it back. I will buy Langbu, and I will ridicule the poems about flowers in Xuandu. I am not happy in power and will stab Bozhou back. On the basis of mother's old age, Pei Du changed to Lianzhou, Qiankui and Erzhou. After a long time, he was recruited as a doctor. He also revisited Du Xuan to watch poems and divided the company into the East Capital. Academic qualifications are still recommended for Langzhong and Ji Xian. Degree, out of Suzhou, moved to Youzhou, with two states, moved to the prince guest company. I am good at writing poems, especially in the late festival. Unfortunately, sitting on waste and suppressing non-cooperation are based on articles. With Bai Juyi, he got a lot of rewards. Juyi tasted his poem: Singing with Bai Juyi, the world called it "Bai Liu". Bai Juyi called it a "poet". Liu Pengcheng Mende was also a great poet. Its front is looming, and its bravery is even smaller. He also said that his poems should be protected by sacred objects, which is highly valued by celebrities. In Huichang, we will check the history of the Ministry of Justice. At the age of 72, he was awarded the book of ministers. Eighteen volumes of poetry, now twelve volumes.

There are many controversies about Liu Yuxi's ancestral home. Some people say that he is from Luoyang, some people say that he is from Pengcheng (now Xuzhou), and some people say that he is from Dingzhou and Zhongshan. According to relevant historical records, Liu Yuxi is a descendant of Xiongnu, and his seventh ancestor, Liu, was born in the Northern Wei Dynasty. He moved to Luoyang with Emperor Xiaowen of Wei and later changed his surname to Han. Father Liu Xu moved eastward to Jiaxing to avoid the Anshi Rebellion, and Liu Yuxi was born here, so Liu Yuxi was "born in Xingyang and occupied Luoyang". About saying that he is a "Pengcheng native", after investigation, he said that he was from Bai Juyi, Quan Deyu and others. That just followed the custom of "all names are salty" (history). Therefore, the statement that "Liu Yuxi is from Pengcheng" is inaccurate.

To say that Liu Yuxi is from Dingzhou, Zhongshan, Zhongshan Wuji, we have to start with his seventh ancestor Liu Liang. During the Zhou and Han Dynasties, Dingzhou and Wuji were the territory of Jizhou, and Wuji was also the territory of Dingzhou. Liu Liang was originally the secretariat of Jizhou, riding a regular servant, and later moved to Luoyang in the Northern Wei Dynasty, and Liu Liang's family also moved to Luoyang. According to the Summary of the General Contents of Sikuquanshu, the collection is divided into categories: "The original name of the book Yuxi was Pengcheng people, Gai County View. In fact, the Wuji people in Zhongshan are also called Zhongshan Collection, which is also built by it. " In addition, the Qing Dynasty also published the Dictionary of Historical Figures in China and the Dictionary of Historical Celebrities in China. After repeated verification and consultation by relevant experts, it is confirmed that Liu Yuxi's ancestral home is Wuji, which is justified.

There are three kinds of existing ancient books in Liu Yuxi's collection: ① Dong's engraving (1 138) in the eighth year of Song Shaoxing, a small seal script, which Xu Hongbao has photocopied. In the 13th year of Xichun (1 186), Luyou was re-engraved according to the Eastern edition, which was called "the reduced edition". Block printing, which has been popular since Ming and Qing Dynasties, basically belongs to this system. (2) The Collected Works of Liu Mengde, an engraving of the Song Dynasty in Chonglan Museum, Fukui, Ping 'an, Japan, is a large-character version of Shu, which is now a photocopy of Dong Kang and a condensed version of the Commercial Press. ③ Collected Works of Liu Mengde (Volume 1-4), and Jian 'anfang Block Edition in Beijing Library. Jin Mao, Hui Dong, He Chao, Feng Hao, Huang Pilie and others in the Ming and Qing Dynasties preliminarily sorted out Liu Yuxi's books, but most of them were manuscripts, which were not widely circulated. The existing editions of Liu Yuxi's collected works are: Four Editions, Liu Mengde's Collected Works, Four Notes, Liu Binke's Collected Works, Collection Integration and Liu Binke's Collected Works. There is also the proofreading of Liu Yuxi's collected works. ? Liu Yuxi's life story can be found in the old and new biographies of Tang Dynasty, and Jia (called Jia) compiled by Tang Dynasty records Liu Yuxi's conversation about creation and learning in his later years, which is quite informative. The Chronicle of Liu Yuxi written by Bian, a modern man, has done a lot of textual research on Liu Yuxi's life and various historical materials. "Humble Room Ming" was selected as the first of the "two short essays" in Lesson 23 of the first volume of Grade 8.
