Biang Biang Noodles
Xi'an's most famous noodle dish features hand-pulled noodles as wide as belts, topped with chili oil, vinegar, garlic, and vegetables. The name "biang" mimics the sound of the dough slapping against the counter as it's being pulled.
"The character for 'biang' is so complex it's not even in the computer! It has 58 strokes and is probably the most complicated Chinese character."
