Tulou is an ancient and remarkable residential heritage that has garnered global attention for their distinctive form and spatial layout that serves both defensive and settlement purposes. This paper provides a comprehensive analysis of the current preservation status of tulou, based on a field investigation of 83 officially recognized cultural relic protection units and immovable cultural relic tulou in Raoping County, Chaozhou City, Guangdong Province. This study focuses on primary damage conditions such as adding doors and windows on external rammed earth walls, replacing roofing materials, additional construction and overall reconstruction, while also revealing the mechanism of hollowing destruction. The study proposes utilizing the "Rural Revitalization" initiative, which is currently being vigorously advocated by the government, as an opportunity to introduce diversified functions into the protection and revitalization of tulou buildings. This will ensure that the tulou are preserved to their fullest extent while also allowing them to continue serving contemporary community life and establishing a new spiritual connection with modern-day villagers. This study offers realistic and comprehensive insights into the current state of tulou heritage preservation, as well as active and effective guidance for preserving and renovating not only tulou but also other residential architectural heritage around the world.
