The "watch the water" Q comment certainly comes to mind, as do biblical end times references to fire, flood, earthquakes, pestilence. A Three Gorges Dam failure could wipe out hundreds of millions of innocent Chinese. I translated many of the Chinese Twitter comments, some are apathetic, some hope it happens and "cleans up China", some praying the dam holds (to whom I dunno). A product of living with 1.4B other Chinese I guess. Apparently for many " Chinese Lives Don't Matter"
