The operation of local post stations in the Qing Dynasty is an important issue in the study of the history of the postal system in the Qing Dynasty.In the middle of the Qing Dynasty,the monthly payment regulations for post stations in Xihe County followed the principle of"daily rotation according to the village and the household",and according to the size of the area of the thirteen villages and the amount of grain in the field,the post station service was evenly apportioned,and the payment dates were divided.To alleviate social contradictions and ensure the smooth operation of the postal stations,the state and county officials took the lead in formulating the regulations of the postal stations with the gentry of the county,which ended the disorderly and chaotic situation and lead to a process of"establishment-elimination-restoration".In the process of moving from disorder to order,the state rulers,local officials,and grassroots gentry and the common people,in consideration of their individual interests,interacted and compete around the post station officers,which led to disputes and lawsuits in lijia.This empirical study reveals the interaction between the state and local society in the management of postal stations in Qing Dynasty prefectures and counties,and reflects the transformation of the national and local financial systems shown by the reform of postal station service.
