There is a special kind of noodles in Xiangshi province, where Xi'an is located, in Western China. Called biang biang mian (Chinese for noodles), this is considered by the Chinese to be one of the ten wonders of China.

The special significance of these noodles is emphasized in part by the Chinese character for "biang":

One of the most complex characters in contemporary Chinese use, this character is not found in modern dictionaries or even in the Kangxi dictionary which is suppose to be the definitive compilation of traditional characters in the Chinese language. It is written in 57 strokes. No Chinese that I have met, including some very educated people, knew how to write this character. In fact, it is so complicated that there is a little ditty that people memorize in order to remember how to write the character (I want to try it here to see if I can get some Chinese on this site).

Traditional 一點上了天,黃河兩道灣,八字大張口,言字往進走,你一扭我一扭,你一長我一長,當中加個馬大王,心字底月 字旁,掛個丁丁叫馬杠,坐着車車逛咸陽。

The noodles are flat, thick, and long. It is sort of fried with all sorts of materials. Quite chewy and filling, biang biang mian is usually served in a huge dish and usually suffices to feed half a dozen persons in one sitting.
