Guo Kui, a well-known snack in Qianxian County, is thick in the middle and thin on the verge with designs of the wheel on the surface. It is crisp and tasty and is always a good present for friends and relatives. When it is made, the wheat flour is mixed with a minimum amount of water and then baked over low flame so that it is easy to be stored and handy to take because it contains very little moisture. That is why it is often the custom of the local people of Shaanxi to travel with it as their food. Guo Kui is one of the "Ten Strange Features" in Central Shaanxi and it is often described as big as a lid of a wok.
