During Yi Bingshou's tenure as magistrate, there were always some literati visiting him because he loved painting and made achievements in official documents. Out of courtesy, they are bound to stay for dinner after the visit, so his chef is very busy. Often, one seat has just left a wave of guests, and then the second wave of guests comes again. Adult Yi Bingshou found his chef so busy, and it was because of eating that he felt very hard.
So he used his brain and came up with a way to mix flour and eggs with water. Roll it into a ball, dry it in the sun, fry it in the oil pan, and pick it up when it is golden. So when the guests come, they can directly take out the noodles and put them in a bowl, using the method we are making instant noodles now. Then you can quickly make smooth and delicious meals. It is very convenient to entertain sporadic tourists with such noodles, which greatly reduces the workload of chefs.
Then after this method of making instant noodles spread, many people rushed to follow suit, so people called instant noodles invented by Yi Bingshou as instant noodles or Yangzhou noodles.
