Go to Yichang to attend a meeting of a group of dam experts. On the plane, sitting next to me was a Japanese dam expert. I asked him: How long is the design life of the dam in Japan? He said: Generally it will be 100 years. The opinion of a Chinese expert who specializes in assessing the safety of the dam is different from him: There is a hundred-year-old dam around.
