The word biang does not exist in dictionaries or computer fonts, so it can only be replaced by pinyin. Biang's spelling can be quickly memorized in a jingle: a minute flies to the sky, the Yellow River bends twice, the eight-character mouth is wide, the words go in, the east twists and the west twists, the left is long and the right is long, there is a horse king in the middle, next to the moon, and a sesame candy is left at the bottom of my heart.

Legend about biangbiang noodles:

The formation of the word biang began with Qin Shihuang. It is said that in the Qin Dynasty, there was always an old man pushing a car along the street in Xianyang to sell biangbiang noodles. One day, Qin Shihuang was tired of eating delicacies, and at that time he had no appetite at home and abroad, so ministers began to look for delicious food everywhere.

A minister found this noodle stall with a thriving business and bought a bowl. Qin Shihuang had a big appetite. After eating, he asked, "What is this? It's delicious, "the minister replied to biangbiang's noodles. The first emperor thought that since he became imperial food, he could no longer make it so easy for civilians to eat, so he gave him a complicated name, deliberately making it difficult for civilians to write this word.
