First of all, there are obvious differences in the geographical location inside and outside the customs. Guanzhong refers to the area within the Great Wall, including Beijing, Tianjin, Shanxi, Hebei and other places. Commissioner refers to areas outside the Great Wall, such as Inner Mongolia, Liaoning, Jilin and Heilongjiang. Due to different geographical locations, there are also great differences in climate, natural environment, history and culture.
Secondly, the human history inside and outside Shanhaiguan Pass also has different characteristics. Shanhaiguan is the political, economic and cultural center of China and the birthplace of Central Plains civilization since ancient times. There are many famous historical sites in the pass, such as the Forbidden City, the Temple of Heaven and the Summer Palace. These scenic spots attract a large number of tourists.
Commissioner is an important part of China's frontier, with a long history and unique national culture. For example, Mongolian, Manchu, Korean and other ethnic minorities live together outside the customs, leaving many unique cultural heritages.
In addition, there are differences in economic development between the customs and the customs. As the economic center of China, with advanced technology, high productivity and perfect infrastructure, Guannei is the main force of China's economic development. Commissioner is a treasure house of China, rich in natural resources such as minerals, forests and grasslands, and an important energy base and agricultural production base in China.
Historical origin
When the Qin Dynasty unified the six countries, Xianyang and Xi 'an were the capitals of the Qin Dynasty and later the Western Han Dynasty, so this place was called "Guanzhong". At that time, the concepts of Guanzhong were "Qianguan (now Fengjie in Chongqing), Yun Guan (now Yunxian in Hubei), Wuguan (now Feng Dan in Shaanxi), Hanguguan (now Lingbao in Henan) and Linjinguan (now Dali in Shaanxi)".
This area includes the Jingwei Plain in central Shaanxi and the vast area of Bashu in Hanzhong. At that time, Guanzhong area was also called "inside the pass" because of its capital, and the area east of these passes was called "outside the pass". During the period of Emperor Wu of the Han Dynasty, there was a famous soldier named yangfu who made several contributions, but his home was in Hongnong, east of Hanguguan.
General Yang was ashamed that his home was outside Shanhaiguan Pass, and asked Emperor Wu of the Han Dynasty to move his home to Shanhaiguan Pass, even willing to hand over his property to the state. Of course, later, Emperor Wu of the Han Dynasty followed suit and fulfilled Yang's servant. This matter is recorded in detail in the book of Emperor Wu of the Han Dynasty: "When Yang Fu, a general on the ship, made great contributions, he was ashamed to be an outsider."
