As an important carrier of rural social relations, water distribution links the interaction between individual members and rural communities. This study is based on the practice of water distribution in WM villages in the northwest region of Yunnan, and delves into the dynamic social relationships in the evolution of water distribution. Research has found that accuracy and presence are the two core elements of water distribution operation. Accuracy relies on precise time cells to generate certainty and standardization of member actions, which are generalized into certainty and standardization through long-term production practice, and ultimately form the foundation of rural ethical regulations. Presence, on the other hand, takes the bodies of rural community members as the material carrier, relying on their physical participation in practice to cultivate a sense of community and ultimately generate a social organizational system for rural communities. The regulation of rural ethics constitutes the value scale and normative system of rural society, while the social organization system of rural communities constructs an interactive network of community organizations, which under the joint action of the two, maintains the stability of rural communities. The rational choice under the market economy and the intervention of administrative forces are the two major incentives for the evolution of water distribution. The rational choice under the market economy leads to the loose connection between water distribution and land, reducing the necessity of water distribution. The intervention of administrative power means that the intervention of administrative power directly damages the autonomy and “self” needs principle of villages, and shakes the civil society foundation of water distribution. With the long-term separation of the labor force and the land, the standardization attached to the land is significantly weakened, the accuracy in water allocation is weakened, and the presence is blurred, resulting in the impact on the foundation of rural communities. In the context of rural revitalization, handling the relationship between young people’s bodies and fields is the key to accuracy modern reconstruction.
