Abstract
The people of Dai, Nong and Gaolan in Vietnam is related in blood with the people of Zhuang in Guangxi. In the past they have migrated to Vietnam from Guangxi for the economic reasons, such as making a living or doing business, as well as for the political reasons, such as the border demarcation, ethnic oppression and discrimination policy, war and looting. Although they mainly engaged in agriculture, husbandry and cottage industries, they have made due contributions to the economic construction both in the residence country and the origin country, as well as to revolutionary struggle.
Key words: Vietnam, Guangxi, minority, Zhuang people, Overseas Chinese
