There is an old legend in Daoxiao Noodles: Mongolian Tatars invaded the Central Plains and established the Yuan Dynasty. In order to prevent the Han people from rebelling and uprisings, they confiscated all the metals in every household, and stipulated that 10 households should use a kitchen knife to cut vegetables and cook in turn, and then return it to Tatar for safekeeping after use.
One day at noon, an old woman made up her face and asked the old man to get the knife. As a result, the knife was taken away by others and the old man had to return. When leaving the Tatar gate, the old man's foot was touched by a thin iron sheet, and he picked it up and put it in his arms. After returning home, the pot kept ringing, and the whole family waited for the knife to cut noodles to eat, but the knife didn't come back. The old man was so anxious that he suddenly remembered the iron sheet in his arms and took it out and said, Use this iron sheet to cut noodles! The old woman saw that the iron sheet was thin and soft, and muttered, "How can such a soft thing cut noodles?" The old man said angrily, "Cut at will." The word "chop" reminded my wife that she put the dough on a wooden board, picked it up with her left hand and held the iron piece in her right hand, and stood by the boiling pot to "chop" the noodles. A one-sided leaf fell into the pot, cooked it, fished it into the bowl, and poured the marinade on it for the old man to eat first. The old man said while eating, "Very good, very good, so I don't have to take the kitchen knife to cut the noodles." In this way, one spread ten times, ten spread hundreds, and spread all over Jinzhong.
