Why is eight hundred Li Guanzhong called Qinchuan?

Shaanxi Guanzhong Plain refers to the Weihe alluvial plain at the northern foot of Qinling Mountains, so it is also called Weihe Plain. It is bounded by Qinling Mountain in the south, Beishan Mountain in the north, Baoji Gorge in the west and Tongguan in the east. It is about 360 kilometers long from east to west, accounting for 19% of the total land area of the province. Since ancient times, the pleasant climate, fertile land and developed agriculture here have laid a solid foundation for the rise of Qin civilization, so it is called "800 Li"

The Qin Dynasty was the first unified dynasty in China, and its capital was located in Xi City, Shaanxi Province. After the demise of the Qin Dynasty, the later Han Dynasty also set the capital in Xi 'an. Qin and Han dynasties are very glorious periods in Chinese history, so it also gave Shaanxi the reputation of "Guanzhong" in central China.

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" and praised Guanzhong for "fertile land, rich people, numerous chariots, tackling all kinds of difficulties, fertile fields and accumulating abundance", and said that "this so-called abundance is also the master of the world". The farmland is fertile, the people are rich, there are ten thousand chariots and millions of warriors. Thousands of miles of fertile land are rich in products, superior in terrain, convenient and fast. This is the so-called land of abundance, and the world is famous. )

This was much 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.
