The Migration Period affects China as well.

Wu Hu (literally "Five Hu") is a collective term for various non-Chinese steppe tribes during the period from the Han Dynasty to the Northern Dynasties.

Their origin lies outside China proper, but they have gradually migrated into Chinese areas during the years of turmoil between the Eastern Han Dynasty and Three Kingdoms.

The Wu Hu, whom the Han had fought to a standstill, have seized the opportunity afforded by the weakness of the central government to extend their settlement of pastoral lands into the fertile North China Plain.
