This book is the first monograph of its kind in the academic world which comprehensively expounds the new methodology of humanities. The quadruple-evidence method is one which integrates quadruple-evidences to open up new horizon for interpretation of ancient culture in the three-dimensional manner.

The first layer of evidence refers to documents passed down from the past; the second layer of evidence refers to local written materials; the third layer of evidence includes oral legends of anthropology and folklore and etiquette in the living folk customs; the fourth layer of evidence refers to those ancient objects and images either unearthed in archaeological excavations or handed down from the past. The book consists of theoretical explorations and their applications in individual cases.

While the first part studies the academic evolution, theory and methodological value of the quadruple-evidence method, the second part, in using the method in different cases, explores different historical and cultural phenomena in the history of China, attempting to extend the frontier of the origin of civilization from the approach of mythological study. .
