A 2022 institutional museum directory describes the Sanjiang Dong ecomuseum through the relationship between an information centre and a village network along the Miaojiang. Historical fieldwork locates this network in the Dudong area, distinct from Chengyang's familiar bridge and village cluster.
The museum's subject extends beyond an exhibition building. Houses, tools, textiles and the knowledge of their users belong to a wider inhabited setting. The centre gathers information; the villages give that information a relationship with places and people.
