an end; they disappeared so completely that thereafter we no longer
find the term Hsien-pi in history. Not that they had been exterminated.
When the social structure and its corresponding economic form fall to
pieces, there remain only two alternatives for its individuals. Either
they must go over to a new form, which in China could only mean that
they became Chinese; many Hsien-pi in this way became Chinese in the
decades following 384. Or, they could retain their old way of living in
association with another stock of similar formation; this, too, happened
in many cases. Both these courses, however, meant the end of the
Hsien-pi as an independent ethnical unit. We must keep this process and
its reasons in view if we are to understand how a great people can
disappear once and for all.

The Huns, too, so powerful in the past, were suddenly scarcely to be
found any longer. Among the many petty states there were many Hsien-pi
kingdoms, but only a single, quite small Hun state, that of the Northern
Liang. The disappearance of the Huns was, however, only apparent; at
this time they remained in the Ordos region and in Shansi as separate
nomad tribes with no integrating political organization; their time had
still to come.

According to the prevalent Chinese view, nothing of importance was
achieved during this period in north China in the intellectual sphere;
there was no culture in the north, only in the south. This is natural:
for a Confucian this period, the fourth century, was one of degeneracy
in north China, for no one came into prominence as a celebrated
Confucian. Nothing else could be expected, for in the north the gentry,
which had been the class that maintained Confucianism since the Han
period, had largely been destroyed; from political leadership especially
it had been shut out during the periods of alien rule. Nor could we
expect to find Taoists in the true sense, that is to say followers of
the teaching of Lao Tzu, for these, too, had been dependent since the
Han period on the gentry. Until the fourth century, these two had
remained the dominant philosophies.

What could take their place? The alien rulers had left little behind
them. Most of them had been unable to write Chinese, and in so far as
they were warriors they had no interest in literature or in political
philosophy, for they were men of action. Few songs and poems of theirs
remain extant in translations from their langua
