About 1929, Japan introduced crayfish, and crayfish flowed to Nanjing, China via Japan.

China had its own authentic crayfish before crayfish, but because of its strong reproductive ability, this kind of crayfish is more popular in China. Moreover, crayfish were only confirmed to be edible in my country after the 1960s, and then China began to gradually breed this kind of crayfish.

Later, this kind of crayfish began to be bred in many places in the country, and subsequently crayfish could be seen in various restaurants in China. In addition to the crazy love of crayfish by the Chinese, even foreigners are very fond of it. There are no rumors that crayfish are so dirty that foreigners will not eat them.
