As early as before the invention of instant noodles, in ancient times, people in the east and west fried cooked noodles and served them with soup. In China, similar pasta has been called "Yi Mian" or "Yi Fu Mian" (that is, what Taiwan Province called "spaghetti"). According to legend, Yi Bingshou celebrated his mother's birthday at home in the Qing Dynasty. Due to the large number of guests, the chef was in a hurry to put the cooked egg noodles into the boiling oil pan by mistake, so he had to scoop them up and serve them with soup. Because the guests were full of praise after eating, this dish was handed down. Early instant noodles were still packaged with Yi Mian and Yi Fu Mian.
