一般认为,“丝绸之路”是以长安(今西安)为起点,经河西走廊,进入新疆,到中亚、西亚,并联结地中海各国的陆上通道。然而,从长安出发以后,如何到河西走廊,向西途经陇山路段,在哪里越过陇山、在哪里渡过黄河、在陇山以东走向如何等,往往被忽视。关于丝绸之路陇山以东走向研究,集中在张多勇的研究。张先生是我中学时代的老师, It is generally believed that the “Silk Road” starts from Chang’an (now Xi’an) and enters the Xinjiang Corridor through Hexi Corridor to Central Asia and West Asia and connects the land routes of the Mediterranean countries. However, starting from Chang’an, how to Hexi Corridor, west through the Longshan section, where to cross the Longshan, where to spend the Yellow River, east of Longshan how to wait, are often overlooked. On the east of the Silk Road Longshan research, focused on Zhang Duyong’s research. Mr. Zhang is a teacher of my high school era.
