most probably ancestors of the later Turkish peoples. It is not
suggested, of course, that the original home of the Turks lay in the
region of the Chinese provinces of Shensi and Kansu; one gains the
impression, however, that this was a border region of the Turkish
expansion; the Chinese documents concerning that period do not suffice
to establish the centre of the Turkish territory.

(d) In the _west_, in the present provinces of Szechwan and in all the
mountain regions of the provinces of Kansu and Shensi, lived the
ancestors of the Tibetan peoples as another separate culture. They were
shepherds, generally wandering with their flocks of sheep and goats on
the mountain heights.

(e) In the _south_ we meet with four further cultures. One is very
primitive, the Liao culture, the peoples of which are the Austroasiatics
already mentioned. These are peoples who never developed beyond the
stage of primitive hunters, some of whom were not even acquainted with
the bow and arrow. Farther east is the Yao culture, an early
Austronesian culture, the people of which also lived in the mountains,
some as collectors and hunters, some going over to a simple type of
agriculture (denshiring). They mingled later with the last great culture
of the south, the Tai culture, distinguished by agriculture. The people
lived in the valleys and mainly cultivated rice.

The origin of rice is not yet known; according to some scholars, rice
was first cultivated in the area of present Burma and was perhaps at
first a perennial plant. Apart from the typical rice which needs much
water, there were also some strains of dry rice which, however, did not
gain much importance. The centre of this Tai culture may have been in
the present provinces of Kuangtung and Kuanghsi. Today, their
