The recent flood in Wuhan has brought up the old debate of whether the SanXia Project should be built.

Our concern was that decision making has carried too much weight of politics and the personal will of some leader， but there was not enough study of all problems it may cause later。 It would not be a big deal if we worried too much, but it would be a big disaster for China if the decision was too hurry.

So many big dams in the world have caused the different problems that people have not found the solutions.
