According to ancient records, the first people who ate crabs never liked them because they were delicious, but because they hated them. At that time, northerners regarded crabs as monsters and dared not speak. Jiangnan people who eat crabs hate crabs quite much. Eating out of hatred, this situation is mostly similar to that of later people eating locusts.
