Ok I see now the tropical storm swept up from the Phillipines and hit Fujian in the south first before moving on to Beijing. Looks like another one is coming just behind this one in the next few days.
Maybe the chicoms are used to big water? Wasn’t it two years ago that a yard of water fell on the Yangtze drainage and wiped out 80 percent of their agriculture in that basin? That was about the time they started buying US farmland and Smithfield hams.
To save the dam from big water I expect the main action would be to open the locks-—assuming Charlie is there to hit the switch?
