The word comes from a snack "biangbiang Noodle" in Xianyang (Shaanxi Guanzhong folk traditional flavor pasta, especially the flour ground from Guanzhong wheat, usually rolled into wide noodles by hand).

Guanzhong folk song: "a little bit of heaven, the Yellow River and the two bays, the eight-character mouth is wide open, if you go in, you screw, I screw;" You grow, I grow; There is a horse king in the middle, next to the heart of the moon, leaving a hook to talk about sugar, strolling around Xianyang. "

There are many sayings in Guanzhong urban and rural areas, but they are all similar. If you write in mandarin, you will see a simple, dignified and vivid word "biang" in front of you.

Biang biang noodles are famous snacks in Shaanxi Province. This clever and humorous "Biang" combination summarizes the origin characteristics of biang biang noodles, the feelings of consumers, the essentials of production technology, the hard work of raw materials, seasonings and noodle makers, the temperament of Qin people, broad and long mind, angular, bitter and cheerful spirit, and has made Shaanxi people proud of their food culture. Among the top ten monsters in Shaanxi, "face like a belt" refers to this kind of face.
