Shaanxi is mainly divided into northern Shaanxi, Guanzhong and southern Shaanxi. Guanzhong refers to the "four passes", namely Dongguan (Hangu Pass), Xiguan (Great Earthquake Pass), Nanguan (Languan Pass) and Beiguan (Jinsuo Pass). Guanzhong area is located in the middle of Shaanxi Province, including five cities and one district of xi, Baoji, Xianyang, Weinan, Tongchuan and Yangling.

Extended data
Guanzhong is close to Qinling Mountains, and Weihe River passes through it, with rich products and outstanding people. There are natural terrain barriers on all sides, which are easy to defend but difficult to attack. Since the Warring States period, there has been a saying of "one country, four blockades". Therefore, in the Han Dynasty, Zhang Liang summed up the advantages of Guanzhong with "a golden city of thousands of miles" and persuaded Liu Bang to make it the capital of Guanzhong.
During the Warring States Period, Zhang Yi told Qin Chen about the plan of "Lian Heng", praising Guanzhong's "fertile land, rich people, numerous chariots, tackling all kinds of difficulties, fertile fields and thousands of miles, and accumulating abundance", saying that "this so-called rich land is also a country under the world", more than half a century earlier than Chengdu Plain was awarded the title of "Land of Abundance". This is because Guanzhong has become a treasure trove of geomantic omen and the capital of emperors since Zheng Guoqu was restored in the Warring States Period.
