Hairy crabs and crayfish are regional specialties. In the past, due to the restriction of transportation and acceptance, not many people liked to eat hairy crabs or crayfish. Generally, local people fish and eat during the Mid-Autumn Festival, which has little commercial value.

Now these foods are recognized and accepted, which can be said to be inseparable from the developed network and convenient transportation.

As for saying that poor people used to eat hairy crabs, it can't be said that it is unreasonable. After all, catching hairy crabs requires hands-on, and there has been an allusion of "the first person to eat crabs" since ancient times. People don't accept this kind of food very well, and the rich are afraid they are not good at it.
