Yu brought together residents, the local government authorities and private entrepreneurs to rebuild the area, which today is acclaimed as one of the top 10 sustainable developments in the country.
In 2002, Yu submitted a report to the central government on the social impact of the Manwan Dam on the Lancang (Mekong) River, which prompted the government to give the local community 70 million yuan ($8.7 million) in additional resettlement funds to mitigate the negative social impact of the dam.
Yu’s goal is for Chinese NGOs to advocate for the institutionalization, implementation and practice of social impact assessments for the interests of communities that are threatened by dam construction.
Whenever the river broke its banks and flooded the surrounding land, scholar officials of the past would voice their dismay that the channeling method of Sage Yu was not followed.

Yu moved north to settle on the east bank of the river in the present northern Henan, close to Hebei.
