“ The people of Shan-si are great traders, and nearly all the commerce of southern Mongolia is in their hands. A railway connecting the capital with Pekin was opened in 1908. The only wagon road leading into and through Shan-si is the great highway from Peking to Si-gan Fu, which enters Shan-si west of Chêng-ting Fu, and leaves the province at Tung-kwan at the great bend of the Hwang-ho. Transport is chiefly on the backs of camels, mules and asses. ”
