Hakka culture takes the traditional culture of the Han nationality as its core, and the breeding and formation of Hakka culture conform to the laws of cultural development. It is a complete system that integrates Hakka customs, values, and aesthetic sentiments. However, preserving traditional Hakka buildings confronts challenges due to a lack of protection awareness and negative external impacts. It is urgent to explore strategies and approaches for the protection and sustainable development of the Hakka architecture. We conduct ethnographic research methods in fieldwork, which can provide the researchers with detailed and rich resources to further support the architectural analysis of explicit and implicit attributes in Haka historical architectures. On the basis of the concept of cultural inheritance, it is necessary to explore and research the protection and renewal of current historical buildings from the explicit and implicit aspects. Taking the Hakka architecture in Heyuan as an example, preservation and renewal strategies from the view of cultural inheritance theory are proposed, providing a practical reference for solving the problems that arise during historical building protection. Although external factors may influence cultural inheritance during the inheritance process, we must ensure that with complete cultural attributes and in line with the requirements of the times, we integrate diverse cultural inheritance to promote the effective continuation of cultural inheritance.
