Legend of the origin of biangbiang surface

In ancient times, there was a poor scholar in Longdong who wanted to go to Xianyang, the capital, to catch the exam. In order to raise money, he sold a load of salt to Dingbian, ready to take it to Xianyang to sell. When I went to Binxian and Yongshou, I suddenly met robbers and took my salt and dry food. In order to catch the exam, the scholar had to carry the burden and beg along the road.

After eight days and eight nights, he finally entered the capital Xianyang. At this time, he was hungry and thirsty. He happened to see a noodle restaurant. The scholar knew that it was not good for city people to do business and beg directly, so he went forward and asked for a bowl of noodle soup. Drinking noodle soup, the scholar accosted the shopkeeper and asked him why he didn't hang a sign.

The owner said, "My biangbiang noodle shop has long wanted to hang a signboard, but no one can write it." After a moment of meditation, the scholar said, "May I have a try?" The store then asked Xiao Er to prepare pens, ink and paper.

Thinking of the hardships along the way, the scholar immediately murmured: "I picked a burden and traveled around, and arrived in Xianyang on the 8 th;" You crack (Yao), he cracks, and there is a prince in the middle; You are long, he is long, including the king of A Dai; At the bottom of my heart, under the moon, Yue Fei went out of the city with a gun and a spear stuck in the wall; Driving around. "

After that, I wrote the signboard of biangbiang noodles in one go. The shopkeeper was overjoyed and invited the scholar to eat noodles. A big bowl made the scholar eat with relish and praised the noodles. When the scholar left, the shopkeeper blessed him: "If you eat my biangbiang noodles, you will be the first in the exam." .

The scholar bowed his thanks. After that, the scholar really won the first prize and became an official in many places. Since then, biangbiang's reputation has spread to many places.
