Taihang Mountain (Mai) is the boundary mountain between Shanxi Province and Hebei Province, and the length of Taihang Mountain is almost the length of the border between Jin and Hebei Provinces. Such situations also exist in the south, such as Luoxiao Mountain (pulse) between Hunan Province and Jiangxi Province, and Wuyi Mountain (pulse) between Jiangxi Province and Fujian Province.
The Wuyi Mountains are basically in a northeast-southwest direction, starting from the Xianxia Mountains between Fujian and Zhejiang, and extending southwest from Fengling Pass. Wuyi Mountain is generally divided into two concepts: Wuyi Mountain Range and Wuyi Mountain. Wuyi Mountain mainly refers to the northeast section of the Wuyi Mountain Range, that is, the Wuyi Mountain Range managed by Nanping City, Fujian Province, and the main peak is the Huanggang Mountain at an altitude of more than 2150 meters (the length is different). The Wuyi Mountains go south from Tieniu Pass, pass through Ganjia Pass and Jigong Pass, and then connect with Jiulian Mountain on the border between Guangdong and Fujian, with a total length of more than 500 kilometers. And these more than 500 kilometers are basically the length of the border between Jiangxi Province and Fujian Province.
Interestingly, Wuyi Mountain (hereinafter referred to as the Wuyi Mountains) is not only the boundary mountain between Jiangxi and Fujian provinces, but also the boundary mountain of the rivers of the two provinces. Many rivers in Jiangxi Province, and many rivers in Fujian Province, are separated by a not-so-wide Wuyi Mountain. The rivers of Jiangxi Province rush north to join the Yangtze River, and the rivers of Fujian Province roll into the sea in the east. Fujian Province, abbreviated as Min, is directly related to the Minjiang River, which is the largest river in Fujian Province.
The Minjiang River has three major sources, the north is jianxi, the middle is Futun creek, the south is Shaxi, and the three streams (Futun creek first confluence with Shaxi) are called Minjiang river after the confluence of Yanping District of Nanping City. Although the source of the three streams is far away, they all originate on the Fujian side of the Wuyi Mountains. In addition, there is a large river in the southwest of Fujian Province, that is, the Ting River, which also originates on the Fujian side of the Wuyi Mountains, flows from north to south, and enters the eastern part of Guangdong Province, called the Han River, and enters the sea in Shantou City.
The situation is similar in Jiangxi Province. The largest river in Jiangxi Province is the Ganjiang River, an important tributary of the Wanli Yangtze River, and Jiangxi Province is referred to as Ganjiang, which is also directly related to the Ganjiang River. The Ganjiang River is called ganjiang river above the main urban area of Ganzhou City, and there are two sources, the south source is Zhangshui, and the east source is Gongshui, which is the source of the Ganjiang River. Gongshui has two branches, called Meijiang (connecting to the Qin river) in the north and Mianshui in the south, and both the Qin river and the Mianshui river originate on the jiangxi side of Wuyi Mountain.
The great rivers in Jiangxi Province also include the Fu river and the Xin River. The source of the Fuhe River originates in Guangchang County, Jiangxi, on the west side of Wuyi Mountain, and several other small sources of the Fuhe River also originate on the west side of Wuyi Mountain. There are many tributaries of the Xinjiang River, and these tributaries also originate from the Jiangxi side of the Wuyi Mountains. The source of the Jiangxi water system is very close to the source of the Fujian water system, but it has the meaning of "old and dead do not communicate with each other", and the ends of the world are separate.
WuyiShan is the boundary mountain between Jiangxi and Fujian provinces, and is about a thousand kilometers away from Xuzhou City in the northwest of Jiangsu Province, and it seems that the two places have nothing to do with each other. But there is one person who associates Xuzhou with Wuyishan. Pengzu, xuzhou ancient name Pengcheng, originated from the Great Peng State built by Pengzu. At the same time, it is also this Peng Zu who is good at cooking and health, folklore has it that he lived for eight hundred years, and he is also known as the founding father of Wuyi Mountain. The name of Wuyi Mountain is directly related to Peng zu. According to legend, Peng Zu brought his two sons to this mountain range between Jiangxi and Fujian, because the names of the two sons, one called Wu and the other called Yi, were called Wuyi Mountain.
Regarding the name of Wuyi Mountain, there is also a theory that the mountain is really called Huyi Mountain. During the Zhou Dynasty of the Shang Dynasty, the Hufang people, who were active between the south bank of the present-day Huai River and the north bank of the Yangtze River, migrated to this mountain range at the junction of Gansu and Fujian, called Huyi Mountain. In the Tang Dynasty, Huyishan had to change its name. Why? The ancients paid attention to avoiding the name of the emperor, and once the new tianzi ascended the throne, not only the names of the courtiers and the emperor had to be changed, but also the place names.
Li Yuan's grandfather, Li Hu, one of the Eight Pillar States of the Northern Zhou Dynasty in the Southern and Northern Dynasties, was made the Duke of Tang for his outstanding service. After Li Yuan established the Tang Dynasty, he naturally banned all the "tiger" characters in the world. Therefore, in order to avoid Li Hu's name, Huyi Mountain became Wuyi Mountain. As an animal tiger, it is also necessary to avoid the name of Li Hu, which is commonly known as a big insect in the jianghu.
Due to the existence of Wuyi Mountain, Fujian Province, which is also known as "eight mountains, one water and one field" with Guizhou Province, was very inconvenient to communicate with the Central Plains (Hunan and Jiangxi) under the conditions of backward transportation in ancient times. The ancients called Fujian an indisputable place for soldiers, and a big reason was that Wuyi Mountain blocked communication with the Central Plains. Therefore, from ancient times to the opening of the railway, Fujian has been a relatively closed area. Since the Tang Dynasty, the jurisdiction of the Fujian Observers has been exactly the same as it is now, and the following five dynasties of minguo, Song, Yuan, Ming, and Qing dynasties have hardly changed. What has changed is only due to the development of the economy, the increase in population, and the increase in the number of states and counties.
In 1958, the strategically significant Yingxia Railway (Yingtan, Jiangxi and Xiamen, Fujian) passed through the majestic and dangerous Wuyi Mountains, linking Fujian, a "place of indisputable soldiers", with the rest of the country. Since then, the Changfu Railway from Nanchang, the capital of Jiangxi Province, to Fuzhou, the capital of Fujian Province, and the railway from Ganzhou to Xiamen via Fujian Longyan in Jiangxi Province, all pass through the Wuyi Mountains, which are no longer an insurmountable barrier for exchanges between Fujian and other parts of the country.
