During the Three Kingdoms, the Eastern Jin Dynasty, the Southern and Northern Dynasties, the Five Dynasties and the Ten Kingdoms, although there were countless heroes or Man Zi proclaimed themselves emperors, they all hid in small buildings and became unified, so they could not be called real emperors.

In fact, in the Southern Song Dynasty, most of the land in the north and the Central Plains was ruled by the Jin regime established by Jurchen (later Mongolian regime), so it can't be called a real emperor. So far, no scholars have raised any objection, largely because the history of China is actually only the history of the Han nationality, and the history of China was written by Han scholars. The psychology of the Han nationality makes it so.

The real emperors in the history of China, the ethnic minorities are: Yuan Dynasty-Mongolians; Qing Dynasty-Manchu (Nuzhen Descendants)

In addition:

The Northern Wei Dynasty (Xianbei nationality) began with Tuoba GUI, Emperor Daowu, and ended with Xiu Yuan, the filial emperor, and stood side by side with the Song, Qi and Liang regimes of the Han nationality.

Jin (Jurchen nationality) Taizu Yan Hong Akuta began, and Aizong Shouxu ended, standing side by side with Han nationality in the Southern Song Dynasty.

Although these two minority regimes did not unify China, they were more prominent than the Han regime in the same period in terms of their existence time and ruling area, and also had an impact on the historical process and cultural formation of China.
