County Prince in the Late Ming Dynasty

At the end of the Ming Dynasty, natural disasters caused a series of refugees everywhere, but this small county was the only one with enough food and clothing. What to do about drought? Artificial rain bombs, what to do about floods? Concrete dams are not afraid of any amount of water. Why are you hungry and don't have enough food? Immediately go to the United States to catch 100,000 large carp and several tons of German crayfish. There are also tons of South American beef. Is that enough? Not enough for another big Australian rabbit. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
