Why is the Qing Dynasty called the Qing Dynasty?

In the early Qing Dynasty, the real name was Houjin, which was a khanate established by Nurhachi in the Ming Dynasty. When he arrived at Huang Taiji, he wanted to be emperor. At that time, Fan Kuan, the first minister of the late Jin Dynasty, told Huang Taiji that if he wanted to take the Central Plains, he had to change his country name and surname. Because in the Song Dynasty, the Han people had already forged national hatred with the Jurchen of the State of Jin! He also proposed that the title of Jin State be changed to Qing, and the title of Jurchen State be changed to Ren, both of which belong to water, enough to extinguish Ming (the sun and the moon are fire).

Ancestors of Manchu nationality

Sushen in the pre-Qin period, Lou in the Han and Wei Dynasties, Buji in the Southern and Northern Dynasties and Xiongnu in the Sui and Tang Dynasties are all direct ancestors of Manchu people. The Liao, Jin, Yuan and Ming dynasties were called "Jurchen", and after the Qing Dynasty it was called "Manchuria".
