Duke Zhou dreamed that there was a big fish in the grave, which could fly and bite people. Finally, many people killed the fish.
"Fish" has always been auspicious, because there are "fish" every year, but the fish on your grave likes to bite and fly, which means that this fish is unlucky. What appears on the grave has always been related to future generations, so this fish was killed by everyone, which means that future generations are definitely unlucky, which means that future generations in your family may not be able to become a climate!
