Push And Impact:the Water-powered Trip-hammer And Watermill In Dali Area During Ming And Qing Dynasties Were Studied From The Perspective Of Local Society

water-powered trip hammer and watermill,as the representative of the traditional hydraulic machinery in China,have been created and applied to the field of food production and processing by our ancestors for a long time,not only greatly liberating the labor force,improving the labor productivity,also boosting the development of society and economy.It has become the most widely used and longest applied grain processing machinery in a long historical period before the appearance and expansion of electric machinery.The history of water-powered trip hammer and watermill development in a country,a region and a nation is not only an important part of the history of science and technology in the corresponding country,region and nation,but also an important window into the social and economic history of the corresponding country,region and nation.Dali,located in southwest frontier minority areas of our country,is a geographical unit and economic unit composed of many DAMS.During the Ming and Qing dynasties,the Central Plains dynasty set up a series of measures and systems in Dali,such as the "Weisuo",the "the bureaucratization of native officers " and the establishment of " the Lu Standard Army ",which led to a large number of people entering Yunnan,promoting the development of the watermill directly.While promoting the development of local society,the popularization of water pestle also brought some impacts,which led to new social conflicts-water pestle and irrigation water disputes.This is not only a manifestation of local socio-economic development and progress,but also a problem brought about by local socio-economic development.The article is divided into four chapters: Chapter 1 introduces the types and distribution of water-powered grain processing machines such as water-powered trip hammer and watermill in the Dali region,and examines the appearance of water-powered trip hammer and watermill in the Dali region,while exploring the role of water-powered trip hammer and watermill in promoting society in the Dali region.Chapter 2 combs the development of water-powered trip hammer and watermill in the Dali region during the Ming Dynasty,discusses the causes of disputes and their nature,and compares the case with that of "mill" in the Guanzhong region during the Tang Dynasty.It combines the Ming Dynasty guard system,population,and water engineering construction,and thus provides a glimpse into the local social development of Dali during the Ming Dynasty.Chapter 3 cards the development of water-powered trip hammer and watermill in Dali during the Qing Dynasty,and discusses the social changes in Dali during the Qing Dynasty around the case of "water pestle and pestle" in the Dali region.It also discusses the social changes in the Dali region during the Qing dynasty,including the migration,population changes and people’s agricultural production and life due to the "the Lu Standard Army" and " the bureaucratization of native officers " in the Qing dynasty.Chapter 4 explores the decline of the water-powered trip-hammer and watermill in the Dali region in modern times and systematically carding the history of the development of the water-powered trip hammer and watermill in the Dali region,thus exploring the interactions between the Dali region and the Central Plains.
