This article contributes to the large-scale engineering scholarship by revealing the labor practices involved and the state's role in shaping them. It provides a history of labor formation through earthwork technology in China's 1950s Huai River Control Project. The Communist Party's approach to engineering and labor differed from its Nationalist predecessor's. The party mobilized millions of peasants to dig and move an astronomical amount of soil in a few years. This herculean feat was made possible by promoting "work methods" to encourage peasants' self-Taylorization. The campaign aimed to cultivate a habit to work efficiently in mass-scale collaboration under external instructions. Through promoting work methods, state-appointed cadres assumed a tutelage role that allowed them to replace labor foremen. A hierarchical cadre-laborer relationship emerged from the same labor process that changed the nation's landscape.
