The Qin dynasty unified the world, but unfortunately, the country's throne was short, the second child died, and the cruel rule did not attract much recognition from the public. The Western Han Dynasty was the first unified dynasty ruled for a long time. After Liu Bang entered the customs, China entered its heyday. It is still highly recognized by the Chinese people that the Han Dynasty expanded its territory and defeated the Xiongnu. Although Chen Sheng and Guangwu put forward the slogan "A king's marquis is better than a general", not many people have experienced the change of dynasties, and no one wants to be an emperor in later generations.
At the end of the Qin Dynasty, there was chaos in the world. In the end, Liu Bang defeated Xiang Yu in the Chu-Han period and won the world. He established the Han Dynasty with Chang 'an as its capital, known as the Western Han Dynasty in history. In addition, the early years of the Eastern Han Dynasty, which lasted for more than 400 years, was the most advanced civilization in the world at that time, leaving such a powerful oath: "Those who do not obey the strong Han will be punished even if they are far away." The Han dynasty had a far-reaching influence on the history and people of our country, and the Han nationality began to emerge from the Han dynasty. When Liu Bang founded the Han Dynasty, why did he choose the word "Han" as the country name?
Hanzhong, formerly known as Nanzheng, is located in Hanzhong Basin in the north of Shaanxi Province, with Qinling Mountains in the north and Bashan Mountain in the south. Hanjiang River is the largest tributary of the Yangtze River, which flows through this area. Hanzhong is named after Hanshui River. The Han River is now the Han River. It is often called "Jianghuai Han" with the Yangtze River, Huaihe River and Yellow River. This is a very important river in Chinese history. Hanjiang River originates from the northern foot of Qinling Mountains. It has three sources: the huge water in the north, the sunshine in the north and the Daiyu River in the north. It mainly comes from the sunshine water in the north of ningqiang county, Zhongshan City, Shaanxi Province. The Hanjiang River flows westward through Shaanxi and Hubei provinces, and finally joins the Yangtze River at Longwang Temple in Hankou, Wuhan, with a total length of 1.577 km.
On the banks of the Hanshui River, Xiao He chased Han Xin under the moon, worshipped the commander-in-chief and shook the three armies. Han Xin built a plank road in the Ming Dynasty, crossed Chencang in the dark, and came out of Hanzhong to help Liu Bang build the world and the Han Dynasty. Liu Bang reached Chencang (now Baoji, Shaanxi) by using the ancient Han River channel. The ancient water transportation of Hanjiang River provided great help for the logistics support of the army. Hundreds of years later, Liu Bei imitated Liu Bang, dominated the Han Dynasty, regained the Han Dynasty and became the king of Hanzhong, but ended in failure. It's not that Liu Bei doesn't work hard, nor that he doesn't have a good general. The great reason is that the Han River changed after the Wudu earthquake, and the Western Han River can no longer provide water transportation convenience for military logistics.
The geographical position between Han and Han is superior. It is an important road between Guanzhong (Central Plains) and Bashu. Shu Dao is difficult, but it is difficult. Hanzhong mountain is high, easy to defend but difficult to attack. The rich and fertile land in Hanzhong has greatly enhanced Liu Bang's cultivation and strength, and he has the capital to go out and Xiang Yu to dominate the world. So the fate of Han Dynasty, Hanzhong and Hanshui is different. Without Hanzhong and Hanshui, there would be no Hanzhong. Without the Han Dynasty and Hanshui River, there would be no Han Dynasty established by Liu Bang, which influenced the history of China for two thousand years. Liu Bang's name is "Han".
