In the early Qing Dynasty, Huang De, a famous chef in Suyu County, was famous for cooking pig's head meat. Emperor Qianlong toured Jiangnan and passed through Suyu. Local officials ordered Huang De to cook, which was praised by Emperor Qianlong and made him famous. After emperor Qianlong tasted it, Huang De poured the leftover broth into the newly cooked pig's head broth, so he left a bowl of broth every day and mixed it into the new soup, which was passed down from generation to generation. It is also because of Huang De's nickname puppy. Therefore, it is called "dried soup stock" or "yellow dog" pork head meat. The characteristics of this dish are: crispy, tender, bright red, fat but not greasy. This dish is listed as a famous dish in Jiangsu. (Suqian)
