South China and Vietnam during Ming and Qing period

我收集了有关明代中国与越南的外交关系的文献资料，通过仔细阅读这些文献资料，以国境外当地人民的活动为重点，描绘了边境地区人民的基本生活和社会的实际情况。特别是，我展示了那些属于泰国民族的人，他们在中国被划分为壮族，在越南被划分为农族或泰族，他们在两国关系中发挥了重要作用。

I have collected the documents concerning the diplomatic relationships between Ming China and Mac Daiviet, and by careful reading of them, focusing on the activities of the local people beyond the state border, I have depicted the actual situations of the basic life and society of those people in the border area. Especially, I have demonstrated how those people who belong in Thai ethnicity, and are contemporarily classified into Zhuang in China, and into Nung or Tay in Vietnam, played an eminent role in the relationships between the two countries.
