I've missed this for soooo long,some local food in my hometown😭😭😭 It's called 豆皮,not the same one in Wuhan.The one in Wuhan is slices of tofu, and this one is a noodle-like food made of rice or with some other materials such as corn, potatoes, mung beans, etc.. About the reason why its main ingredient is not beans, but it is called this.Primarily a homophone from 漏斗.It was originally called 漏斗皮,or for short like 斗皮,And then because 豆 It's more like a word for food,the word gradually became what it is now.
