A long time ago, Ii Changnan Jin was living by the Yangtze border with a mother and son. A year in winter, snow flies, old mothers get sick and want a little shrimp by the river. After listening, the son came to the river cold and tried to get shrimp for his mother. It was discovered by the river that the river was already frozen and that no matter how hard he could hit it. In a hurry, he undressed his clothes and lay on the ice and melted it with his body. Not long ago, he fainted. In the dream an old man with a white beard said to him, “Are you not a shrimp?” I taught you that the young man suddenly woke up, ran home to make shrimp the way the old man did, and gave it to his mother, who came back with a miracle. Subsequently, shrimp production methods became popular and were referred to as “creas shrimp” or “creas shrimp”。
