The Chinese, ever since the first century of our era, have called the countries which we to-day name Kashgar and Sungaria, "routes." They referred them to their relative position on the two sides of the Tian-Shan, and called our Sungaria, Pe-lu, " northern route," and our Kashgar, Nan-lu, " southern route." The Turks gave other names to these countries; they called the northern route besh-balik, "the five cities," Pentapolis; the southern route was alti-shehr, " the six cities," Hexapolis.
