宋代是中越双边关系的草创期,各种外交制度和模式都处在摸索和调适之中,其中就包涵了安南使节使宋路线的选择。廉州道是北宋前期安南使节优先选择的路线,但钦州道后来居上,取而代之,成为宋代安南使节使宋的主要线路,邕州道凭借其全程陆路的优点,地位亦有日益增重的趋势。路线选择背后蕴含着深刻的历史和自然背景,如历史的惯性,交通干线和贸易中心的变迁,接待花费与交通成本,以及气候、地形和路线距离等自然因素。 The Song Dynasty was the grass-making period of the bilateral relations between China and Vietnam. Various diplomatic systems and models were in the process of exploration and adjustment, which included the choice of Annan envoys to make the Song line. The state route of Lianzhou was the preferred route for the Annan envoys in the early Northern Song Dynasty. However, Qinzhou became the main route for the Annan envoys in the Song Dynasty and became the main route for the Song Dynasty. The state of Zhuozhou, due to the advantages of its entire land route, is also gaining ground. Behind the route selection is a profound historical and natural background such as the inertia of history, the changes in the transportation routes and trade centers, the cost of transportation and transport, and the natural factors such as the climate, the topography and the route distance.
