The article is to try to collect and summarize how Hongkeng Village has continued the human settlement system of the ancient village in the stage of aboriginal life and in the stage of tourism, and proposes an NFT-style traditional cultural protection strategy to create sustainable development for local tourism companies' and villagers' incomes. The empirical research method was used to summarize the symbiotic system of the traditional human village settlements based on the analysis of the Hongkeng Village settlement. The literature research method was used to find the research status of symbiotic philosophy at home and abroad. The case analysis method was used to illustrate how the combination of the cultural heritage with the science and technology plays a role in the field of public welfare during the elaboration of the specific NFT applications. As to the foregoing, the article finds that symbiotic units, symbiotic models and symbiotic environments work together to develop the human settlement in Hongkeng Village. This framework guides how to embed the NFT art production structure into the protection system of traditional human village settlements, providing a new perspective for cultural heritage protection of traditional villages in the context of the metaverse era.
