1. The Tang Dynasty was founded by Tang Yao in ancient times. Later generations often call it the Yu Dynasty, and the history is called "Tang Yu". In the early days of Yao's rule, there was no basic national system, and the country was just a tribal association, which was very loose, which was not conducive to the unified management of the country. Therefore, after accumulating certain administrative experience, Yao began to establish a national political system, one of which was to appoint officials according to various government affairs. For the first time in the history of China, he established a relatively systematic political system, which laid the foundation for the emergence of a slave country, known as the Tang Dynasty [1].
The Analects of Confucius Taibo: "On the occasion of Tang Yu [2-3], it was prosperous in Sri Lanka." Biography of Zheng Ji in Historical Records: "Your Majesty wants to be benevolent outside, how can he treat Tang Yu?" "Preface to Historical Records Taishi Gong": "On the occasion of Tang Yu, Shao paid attention to Li Hou and resumed it. However, it emphasizes Li's world. The poem "Qin Yuan Chunshou" in Song and Liu Dynasties wrote: "In Pingzhang, people are like Louis, and the world is like Tang Yu." Guo Moruo's poem "Starry Sky, Son of Solitary Bamboo Jun": "I seem to be before the Tang Yu era."
2. The Yu Dynasty (about the beginning of the 36th century BC-about 265438 BC+the beginning of the 0th century BC), also known as the Yellow Emperor Dynasty and Yu Shun Dynasty, is now Yucheng County, Shangqiu City, Henan Province. It is a dynasty recorded in history books that is older than the Xia Dynasty. In the first issue of Hebei Academic in 2002, Comrade Wang Shumin's academic paper "There was a Yu before Xia, Shang and Zhou Dynasties" was published. "Yu Chao" means "Yu Shun" in history books, referring to Yao Zhonghua in Shun Di. Yao Zhonghua, whose word is Jade, is a tribe of the clan commune. Why is it called Zhong Hua? Legend has it that Shun's eyes are binocular, so the word "Zhonghua" may refer to the Chinese nation of the Chinese nation.
3. Later it was called Xia, Shang and Zhou.
