Answer:
The Five Dynasties and Ten Kingdoms
Explanation:
(907-960 in the narrow sense and 902-979 in the broad sense) was a period in Chinese history that began with the fall of the Tang Dynasty and ended with the Song Dynasty unifying most of the Han lands. The Five Dynasties and Ten Kingdoms were essentially the continuation of the separatist regimes in the late Tang Dynasty and the politics of the late Tang Dynasty. After the fall of the Tang Dynasty, various vassals and towns established themselves as nations. Among them, the countries with strong military power in North China were collectively referred to as the "Five Dynasties," and some were established by Shatuo. Although the "Five Dynasties" seem to be relatively powerful, they are still unable to control the entire Han region. Other vassal vassals, either self-proclaimed as emperors, or the Central Plains dynasty, are regarded as orthodox. Ten of them are older and stronger nations. Collectively referred to as the "ten countries".
