The legend of biangbiang noodles
One day, Qin Shihuang looked at the delicious food cooked by the chef, but he had no appetite at all, so ministers began to look for delicious food all over the street. A minister found a noodle restaurant with a thriving business. He thought: This noodle restaurant is so popular that it must be delicious! So he went back to the palace and told Qin Shihuang. Then, he took Qin Shihuang to this noodle restaurant.
Qin Shihuang tasted it, and his tears came out, but he still wolfed down his noodles (recently, he heard from his father that revolutionary people like to eat Chili, which may be the reason why they can "show off" on the battlefield). After eating noodles, Qin Shihuang wrote a word on the spot-the word above, pronounced "biang" (two sounds). And this face is called "biangbiang face".
