Hanzhong basin, also known as Hanzhong plain, is located in the south of Shaanxi Province, in the upper reaches of Hanjiang River, between Mianxian County and Yangxian County, and between Qinling Mountain and Daba Mountain. It is a faulted basin, a land of plenty and a house of national treasures. Hanzhong is the birthplace of the Han Dynasty, so the local slogan is "the birthplace of the Han family, the cornucopia of China". This couplet is cleverly embedded with the word "Hanzhong Basin".
