At the rebuilding of the Toba empire, however, a good many Hun tribes
withdrew westward into the Ordos region beyond the reach of the Toba,
and there they formed the Hun "Hsia" kingdom. Its ruler, Ho-lien
P'o-p'o, belonged to the family of Mao Tun and originally, like Liu
Yuean, bore the sinified family name Liu; but he altered this to a Hun
name, taking the family name of Ho-lien. This one fact alone
demonstrates that the Hsia rejected Chinese culture and were
nationalistic Hun. Thus there were now two realms in North China, one
undergoing progressive sinification, the other falling back to the old
traditions of the Huns.
