It is officially known as the Sinkiang Uigur Autonomous Region and is also called Chinese Turkistan or Eastern Turkistan. The capital is Wu-lu-mu-ch'i.…Sinkiang is now linked to the Chinese rail network, but west and south of Wu-lu-mu-ch'i transportation is still concentrated along two ancient roads: the north road, which skirts the southern edge of the Dzungaria and connects Wu-lu-mu-ch'i with the Soviet Turkistan-Siberia RR, and the south road, which encircles the Tarim basin.
