Biography of Li Deyu, one of the six major politicians in China

Li Deyu (787–850), courtesy name Wen Rao, was a tang Dynasty politician and literary scholar, a tang dynasty politician and literary figure, the leader of the Li Party in the Niu-Li Party, and the second son of Li Jifu, a Zhongshu attendant. Li Deyu was born in the Western Ancestral House of the Li clan in Zhao County, and in his early years he entered the army as a door shade, and successively served as a school secretary, a supervisor of imperial history, a scholar of Hanlin, a zhongshu sheren, an observer of zhejiang, a soldier's attendant, a zhenghua jiedushi envoy, a xichuan jiedushi envoy, a bingbu shangshu, a zhongshu shilang, a zhenhai jiedushi envoy, and a huainan jiedushi envoy. He went through the four dynasties of Xianzong, Muzong, Jingzong, and Wenzong, and once entered the dynasty as a minister, but due to party strife, he was expelled from Beijing many times. After Emperor Wuzong succeeded to the throne, Li Deyu paid homage to him. He reigned for five years, and was honored as a lieutenant and a duke of wei. Emperor Wuzong's acquaintance with Li Deyu's vassals also became a late Tang dynasty song. After Emperor Xuanzong succeeded to the throne, Li Deyu was demoted to the position of Yazhou Sihu because of his high power. He died of illness in Yazhou in December of the third year of the great middle school (January 850). During the reign of Emperor Yizong, he posthumously restored the official title and gave him the title of Zuo Shu (左仆射). After Li Deyu's death, all the dynasties and dynasties spoke highly of him. Li Shangyin praised him as "The Good Phase of The Ancients" when he wrote the preface to the Huichang Yipin Collection, and in modern times Liang Qichao even ranked him alongside Guan Zhong, Shang Martingale, Zhuge Liang, Wang Anshi, and Zhang Juzheng, calling him one of the six great statesmen of China.

Early life

Since childhood, Li Deyu had great ambitions and painstakingly studied the history of the scriptures, especially the "Book of Han" and "Zuo Zhuan", but he did not like to participate in the imperial examination, and later entered the army as a door shade and became a school secretary. During the Yuan And Dynasties, Li Deyu went to the clan town to avoid suspicion because of his father Li Jifu's worship, and was often set aside by the various clan towns.

In the eleventh year (816) of his tenure in The Yuan Dynasty of Tai Province, Zhang Hongjing left the town of Taiyuan and served as an envoy to Hedong Jiedushi. Li Deyu was made the secretary of the office, and successively appointed Dali commentators and served in the palace. In the fourteenth year of Yuan He (819), Zhang Hongjing stepped down from his post as a returner. Li Deyu was actually given the post of Inspector of Imperial History and returned to Taiwan Province.

In the fifteenth year of Yuan He (820), Emperor Muzong of Tang succeeded to the throne. Li Deyu was summoned to the Hanlin Academy and served as a Hanlin scholar. When Mu Zongshang was in the Eastern Palace, he was familiar with Li Jifu's name, so he attached great importance to Li Deyu and often asked him to draft imperial edicts. Li Deyu was also summoned to the Sizheng Hall to ask for the right, and was given purple clothes and goldfish bags, and later changed to Tuntian Yuanwailang.

In the first year of Changqing (821), Li Deyu commented on the phenomenon of foreign relatives interfering in politics at that time: "In the old practice of this dynasty, horses were not allowed to interact with important members of the imperial court, and the prohibition was particularly strict during the reign of Emperor Xuanzong. In recent days, donkey horses have often gone to the private residences of prime ministers and important officials, sometimes divulging secrets and making friends inside and outside, which is a great drawback.
