Enhancing national cultural self-confidence involves promoting and strengthening the protection and utilisation of traditional national villages. Studying how to protect and inherit the resources of these villages, as well as utilising existing resources in a sustainable manner, poses a challenging issue. Further research is needed to investigate the influence of regional culture on residential buildings in the mountainous areas of the Yao people in Guangxi, and to explore how traditional architectural elements can preserve their cultural essence using modern artistic language. The project aims to: 1. Examine how regional culture influences Yao ethnic minority houses in Guangxi's mountains; 2. Evaluate existing challenges and implement contemporary design for improvement; 3. Create sustainable and culturally significant Yao mountain dwellings. The research collected qualitative data from six towns using a combination of semi-structured interviews, participant observation, and reviewing internet and print news sources. The residential structures in Yaochi Mountain District, Guangxi exhibit unique regional cultural traits, although they also have deficiencies in several areas. This study find that the beauty of the natural environment remains constant but the architectural vestiges and cultural history show remarkable variance, both of which greatly contribute to sustainable development. This study found that traditional villages in Guangxi share a number of characteristics, including a severe deficiency in clean energy and a poor rate of carbon utilisation, during our investigation of the sustainable development of the spatial dimension of the ecological legacy of these communities. According to a weight analysis performed at the sub-index factor level, the variety of building uses is the most important indicator of the spatial sustainability of traditional villages in Guangxi. The outcomes of this study provided a valuable empirical evidence and practical suggestions for areas and nations involved in the preservation of cultural heritage and the investigation of sustainable rural development.
