So-ch'e

Flourishing cotton fields abound also at So-ch'e, Maralbashi (Pa-ch'u), Shan-shan, Su-lo, and Korla.[…] Around a million catties of raw silk reportedly is produced each year from Khotan, Yarkand (So-ch'e), and Su-lo acreage, and a considerable increase is expected; for the provincial Reconstruction Commission has been importing improved silkworm eggs and extending sericulture plots.

Upon emerging from the Kunlun gorges, the Yarkand loses the characteristics of a raging mountain torrent and spreads out in many branches over an alluvial fan to irrigate the Yarkand oasis. The oasis, one of the largest in Sinkiang, contains the towns of Yarkand (So-ch’e) and Tse-p’u (Posgam). Upon leaving the Yarkand oasis, the river flows north past Mai-kai-t’i (Merket-Bazar) and then northeast around the eastern margins of the Takla Makan desert. South of the Aksu oasis it joins the Kashgar, Aksu and Khotan rivers to form the Tarim.

On the south side of the Taklimakan Desert stands a Central Asian oasis, the edge of a dusty city that was once the centre of a great Buddhist kingdom. As early as the second century A.D., Yarkant (Suoju, Shache, or So-ch'e in Chinese) was responsible for ideas and texts that changed the Chinese empire.
