Introduction: Xuzhou people have a fresh soup for breakfast, which has a history of more than 4000 years. Peng Zu, the ancestor of cooking, took a wild chicken soup from Yao and sealed it in Pengcheng. Mountain chicken soup is a soup made of pheasant and millet, which tastes delicious. According to legend, Emperor Qianlong went down Jiangnan Road and passed through Xuzhou City, which has continued to this day. At the end of Qing Dynasty, its ingredients were changed from pheasant to hen and millet to wheat kernel, but its production still did not lose the patriarchal clan system and the flavor still existed.
