Features: The pre-Qin era had the "Gu Feng," a collection of oral traditions passed down by ancient Central Plains ethnic groups, which concentrated certain cultural essences of ancient China. In Yunnan, the Hani, Lisu, Lahu, Wa, Jingpo,, Pumi, Achang, Nu, Jino, Deang, and Dulong ethnic groups have a short history of written language. From a historical perspective, they can be considered as ethnic groups without written language. Their long-standing oral traditions have survived and been passed down to this day, serving as a summary of the spiritual and material cultural theories and experiences accumulated over time. This includes: 1. Primitive thought culture (knowledge system: philosophical thinking and scientific cognition); 2. Traditional value culture (behavioral patterns: ethical norms and belief concepts); 3. Ancient historical culture (social traditions: folk awareness and historical memory); 4. Distant artistic culture (aesthetic experience: aesthetic preferences and entertainment interests). This oral tradition can be regarded as an encyclopedia without written language, serving as the cultural repository of these ethnic groups during their pre-literate era. It is also a part of the culture of the Chinese nation.
