Lu Xun's letter to Cao Juren in June 1933, 18: "The ancients told us how the Tang Dynasty flourished and how the Ming Dynasty was good. In fact, the Tang dynasty was full of nonsense, and the Ming dynasty was a rogue. This kind of object needs to be flashy and show humanity. " This is a famous argument. In the Tang Dynasty, Li was born in a minority nationality. Li Yuan's mother is the sister of Wendi's lonely queen, and she is a minority. Li Yuan inherited Tang Guogong, a famous family in the Northern Zhou Dynasty. At the same time, Li Yuan has been active in Taiyuan, Shanxi and other places, contacting and being rendered by the northwest minority culture. After the founding of People's Republic of China (PRC), various groups in Tang Wenhua merged. This is directly or indirectly related to Li's pedigree and experience.
