Xuzhou local cuisine is partial to that dish.
Xuzhou belongs to the border of four provinces. In the past, the population moved a lot, so the taste was mixed. But I think on the whole, Xuzhou cuisine is characterized by heavy color and spicy and salty taste. I don't think Xuzhou cuisine is biased towards Shandong. I have been to many places. Shandong cuisine is only salty and tastes completely different from Xuzhou cuisine, while Hunan cuisine and hubei cuisine cuisine I have been to are closer to Xuzhou cuisine. I think Xuzhou cuisine is closer to Hunan cuisine.
