— In how far the name of that time was bound to the western mountains is already proved by the observation that the Ts'ung-ling is not mentioned at all in the adjoining mountainous regions to the north and south, viz., first on the line from Wen-su (Uch-Turfan) to the Wu-sun, on Issik-köl. and secondly from P'i-shan (on the Kiliang River to the west of Khoan) viâ Wu-ch'a to North-western India⁵.
