In 1855,the Yellow River changed its course from Lankao Tongwaxiang in Henan Prov-ince,passed through the North China Plain,and intersected with the canal in Zhangqiu Town,Yanggu,Shandong Province.The intersection of the Yellow River and the Yellow River had an important impact on the development of the social,economic and cultural history of the North China Plain.Its impact is limited by the establishment of the People's Republic of China.In the early stage,due to the frequent breach of the Yellow River,it caused catastrophic hazards such as flooding of farmland and houses,migration of res-idents,and interruption of canal transportation.After the establishment of the People's Republic of Chi-na,the Party and the state implemented various measures to utilize the hydrological resources of the Yellow River,turn harm into profit,and promote the progress and development of the social,economic,and cultural aspects in the areas it flows through.
