Yangchun noodles, also known as "clear soup and smooth noodles", is a major feature of Shanghai. It's a long story The word "long" will last until the time of Qin Shihuang. We know that Qin Shihuang unified weights and measures, but we don't know that Qin Shihuang also unified the calendar. October in the summer calendar is the first month, and this month is also called Xiaoyangchun. The relationship between October and Yangchun was later quoted in Shanghai's Incision, and Yangchun is "ten". In the past, this kind of noodles cost ten pence per bowl, which was the meal of Fu Cha and pawn. Because the smooth noodles don't sound good, the name of the noodles was replaced by the price, which became "Yangchun noodles". In addition, there is another saying that it originated from "Chun Xue". There is nothing in this light, nothing in this snow, so it becomes a face name.
