Why is the Tang Dynasty called the Tang Dynasty? Why is the Li family called the Tang Dynasty?

"Tang" was originally the abbreviation of Tao. It is the name of an ancient tribe who lived in Pingyang (now Linfen, Shanxi) and its leader was Yao, so it was called "". Zhou Chengwang destroyed Tang Yao and named his brother Yu Shu Tang Shuyu. Uncle Yu passed on his son to his father and changed "Tang" to "Jin", which has been used ever since. Later, regardless of the "Tang" and "Tang State" in several places, their fiefs and jurisdictions were all in today's Shanxi. Although Tang Yao perished as early as the Zhou Dynasty, its cultural heritage was inherited. For example, the surname "Li" comes from Dali, who was in charge of the prison during Yao's rule. Their descendants attacked each other and took the official as their surname, so they called it "Li". Later, in order to avoid the harm, the descendants of the "Li family" fled to the new market and ate it in order to survive, so they changed "Li" to "Li". It can be seen that Li is also closely related to Tang.

As far as Li Yuan is concerned, he stayed in Taiyuan in 6 16 A.D. (the 12th year of Yang Di's great cause) and was responsible for suppressing Shanxi insurgents. The next year, when the time was right, he started his army in Taiyuan, and then he took over the world. It can be said that Li was born in Taiyuan, the ancient land of Tang Dynasty. After winning the world, he named the country "Tang", which actually contained profound commemorative significance.
