Hairy crabs and crayfish are regional specialties. In the past, due to restrictions on transportation and recognition, not many people liked to eat hairy crabs or crayfish. Generally, local people catch and eat them during the Mid-Autumn Festival, and they do not have much commercial value.

Now that these delicacies are recognized and accepted, it can be said that it is inseparable from the development of the Internet and convenient transportation.

As for saying that only poor people ate hairy crabs in the past, it cannot be said to be unreasonable. After all, catching hairy crabs requires one’s own hands, and there is a story about “the first person to eat crabs” since ancient times. People's acceptance is not high, and rich people may not like this kind of food.
