Liangpi is a noodle-like Chinese dish made from wheat or rice flour. It is a specialty dish originating from the Chinese province of Shanxi , but has now spread to many other places in China, in particular the northern and central regions. Although liangpi is served cold, they are served in every season, including winter.

　　Chinese people describes liangpi served at Xi'an Famous Foods as "a dish of cold noodles in a sauce that hits every possible flavor category (sweet, tangy, sesame paste and other flavors)Liangpi literally means cold skin, although it has no animal products in it at all.

　　There are several ways of making liangpi:

　　First,wheat or rice flour is turned into a soft dough by adding water and a little bit of salt. Then, the dough is put in a bowl, water is added and the dough has to be "rinsed" until the water is saturated with starch from the dough, turning into a muddy white color. The remainder of the dough is now removed, and the bowl is left to rest overnight at a cool place to allow the dissolved starch to precipitate.

　　The following day, there will be a kind of starch-paste on the bottom of the bowl, with a more or less clear liquid on top, which has to be discarded. Once the liquid has been removed, a small amount of the paste can then be poured into a flat plate or tray, and spread evenly in a thin layer. The whole plate is placed into a large pot full of boiling water, where it is steamed for a couple of minutes, and the resulting "pancake" cut into long pieces vaguely resembling noodles.Mixed with some cucumber, green bean sprouts, put seasoning, salt, chili oil, vinegar,then you can enjoy it.
