Yes, the eldest son, and also the eldest son of Li Yu. Emperor 10 of the Tang Dynasty, who ascended the throne in 779 AD, reigned for 26 years and lived for 64 years. Posthumous title is Emperor Xiaowen of SHEN WOO. Tang Dezong made great contributions to pacify the Anshi Rebellion, but he had doubts about Dezong, unable to solve the contradiction between courtiers, and the political situation was chaotic.
Tang Dezong is an emperor who loves tea. "Sun Huang Wang Fengjie fried tea with crispy peppers and asked for a poem. He said: "Spin the foam into a jasper pool and add brittle powder to make glass eyes. King Fengjie is Dezong. " This passage recorded in Tang Lifan's Ye Hou Jia Chuan Sun Huang Wang Fengjie Fried Tea is a great proof that Tang Dezong loves tea. There are four ways to drink tea in the Tang Dynasty: nunnery tea, boiled tea, fried tea and ordered tea. Tang Dezong should be an advocate of tea cooking, and the "heavy taste" of cooked crisp and pepper can illustrate this point.
Because of his love for tea, Dezong loves me, love my dog, and he appreciates Lu Yu very much. He has The Book of Tea. Lu Yu experienced four dynasties in his life, namely Xuan, Su, Dai and so on, summed up his half-life tea-drinking practice and knowledge of tea science, and wrote a monograph on tea science, Tea Classic. Although Lu Yu didn't pass the imperial examination, Dezong hired Lu Yu without a "diploma" and ordered him to be the master of Taichang Temple (Taichang Temple is the institution in charge of ancestral temple sacrifice in China, which has a lower position among the masters and is in charge of prayer).
About tea, Tang Dezong has a most historic move. In the first year of Jianzhong (AD 780), Zhao Zan, assistant minister of Dezong Household Department, proposed to levy a tea tax in the world, which was the beginning of the tea tax. Although this move opened up financial resources for the Tang Dynasty, it also increased the burden on the people. In the second year of Jianzhong (AD 78 1 year), Gao Yuan, then the secretariat of Huzhou, wrote a poem on Chashan, criticizing tea politics, thinking that tribute to tea disturbed people, and Dezong suggested reducing tea tribute to alleviate people's difficulties.
Tang Dezong era is also a period of great development of tea industry in Tang Dynasty. In the ninth year of Zhenyuan (AD 793), the national tea production exceeded 2 million chengdan, with a per capita income of about 8 kg. According to the per capita quantity, it can be described as "unprecedented" and "no one came after", and it is also a bright spot in the history of tea development.
