古代西方旅行家马可.波罗是世界历史上第一个将地大物博的中国向欧洲人做出报道的人,在他的游记中用了大量的篇幅,对我国的自然和社会作了详细描述。笔者认为《马可.波罗游记》在“匝儿丹丹省和永昌城”一节中,记载了大量元朝时期傣族生活的有关情况,反映出在元朝时期佛教尚未传入勐卯弄,并提出了“匝儿丹丹省”是“盛产酸渣子的傣族地区”的推论。 Ancient Western traveler Marco Polo was the first person in the history of the world to report to Europeans the vast territory of China. He devotes a lot of space in his travelogue to a detailed description of our country’s nature and society . In the section of “Tuan Dandan and Yongchang City”, the author thinks that “Marco Polo’s Travels” records the situation of a large number of Dai people living during the Yuan Dynasty, which shows that Buddhism has not been introduced into Meng dynasty And put forward the conclusion that “Ruan Dandan ” is “Dai area rich in acid dregs ”.
