This book revolves around the marriage, trade and social order of the "Miao" ethnic minority on the Yunnan-Guizhou Plateau, traces the historical changes of the two different exchange forms of the Miao people”s marriage exchange and market exchange, and examines the characteristics and operation of the social order in the Miao people”s society. The case of the Miao people shows that economic development does not necessarily lead to the disintegration and collapse of traditional society. We can not only reform and open up the economy and move towards an open global economy, but also return to the spiritual homeland of the nation and the traditional classical ethics at the same time.
