In the USA way, way back when the Mississippi River flooded EVERY single year and the home owners kept getting PAID by the U.S. government.
Until one year the government said NO MORE MONEY because the river always floods--so MOVE. No more US$$ = people moved.
Those Chinese in the wake of the YEARLY flooding should be moved. China is a big country. There HAS to be some place to move them to.
millions were displaced for this dam.
