When he was eighty years old, he took a beautiful girl from a fisherman's family in the south of the Yangtze River as his concubine. During the wedding banquet, his subordinates flattered him and planned a puffer feast for him. As a precaution, he asked his father-in-law, a young fisherman, to guarantee that he would bring local puffer fish and a chef who was good at puffer fish to Beijing to prepare a meal. On the day of the wedding banquet, dignitaries and dignitaries gathered to congratulate them. When the fragrant stewed puffer fish was served on the table, the salivating guests rushed to eat, and plates of puffer fish were eaten in the blink of an eye. Just when everyone was overwhelmed with beauty, suddenly a guest fell to the ground, foaming at the mouth, twitching all over, and fell unconscious. "Someone has been poisoned!" The wedding banquet was in an uproar and chaos. The minions rushed to the kitchen to catch the cook and the young father-in-law, but they were nowhere to be found. In the panic, Yan Song became furious and asked his concubine: "How to detoxify?" The concubine replied: "There is only yellow soup." So Yan Song immediately ordered to go to the toilet to carry excrement water. He raised his neck, closed his eyes, drank the excrement, and spat out the puffer fish and other food that he had grabbed for food. The wedding banquet suddenly stank to the sky and became a mess. At this time, the father-in-law and the cook, who had gone out to watch the fun, came back. The man who fell to the ground also woke up and told the truth about the matter. However, he came here to relieve himself on business. When he came back, he found that the pufferfish had been wiped out, and he suddenly became angry. Atmosphere, old epilepsy disease relapses. . . This story is widely laughed at but not believed to be true. It was probably made up by some expert who hates the traitors of powerful officials. However, by combining the delicious puffer fish with dirty feces and treacherous people, it ruins the reputation of such a delicacy.
