作为东亚文化圈的代表国家之一,越南自公元十世纪起,就与中国建立了长达千年的宗藩关系。期间,不断有越南使者肩负求封、进贡、答谢等使命,从镇南关出发北上,横跨大半个中国,千里迢迢来到京师之地。他们留下的诗文、日记、使程图等(即通常所说的燕行文献),均从一个异邦的角度,为我们了解古代中国的历史、文化和社会状况,提供了新鲜而弥足珍贵的第一手材料。 As one of the representative countries in the East Asian cultural circle, Vietnam has established a suzerain-vassal relationship with China for thousands of years since the 10th century. During this period, Vietnamese ambassadors continued to hold the mission of seeking letters of seal, tribute and appreciation. They proceeded northward from the Zhennan Pass and across most of China, coming all the way to the capital. Their poems and diaries, their diaries, and so on (commonly known as the Yan-line documents) have provided us with fresh and supreme insight into the history, culture and social conditions of ancient China from an alien perspective Precious first-hand material.
