Wuling, which was visited by the Red Army 70 years ago, is a broken mountain. Generally, the altitude is below 1000 meters, and it is 2000 meters higher. Wuling, as an important geographical dividing line, is not only the watershed between the Yangtze River and the Pearl River, but also the basis for dividing Hunan and Jiangxi provinces and Lingnan administrative regions.
The Red Army made a detour in Wuling for two months. The Red Army chose to March into Wuling, largely because it was far away from the provincial warlord power centers. Until today, Wuling Mountain is still the edge of Hunan, Jiangxi, Guangxi and Guangdong provinces.
Extended data:
Nanling, where Wuling is located, is the watershed between the Yangtze River system (Dongting Lake system-Poyang Lake system) and the Pearl River system and surrounding mountains.
Yuechengling Mountain Range at the western end: Yishui, the east source of Zijiang River in Dongting Lake system, is the source of Xiangjiang River in Xing 'an Dongting Lake system in Guilin, Guangxi. At the same time, Xing 'an and lingchuan county, where the southwest corner of Yuechengling Mountains is located, are the birthplaces of several tributaries of Xijiang River in Guilin, Guangxi.
Therefore, when Qin Shihuang marched south to Guilin, he built a famous Lingqu here to connect the Yangtze River system and the Pearl River system, and transported personnel and materials from the Xiangjiang River system to Guilin, and later established Guilin County. Qitianling is the watershed between thunder water, a tributary of Xiangjiang River in Pearl River system, and dancing water at the source of Beijiang River.
The Dayuling Mountains at the eastern end are the watershed between the source of Ganjiang River in Poyang Lake system and Beijiang River in Pearl River system.
Several other mountains are also such a watershed.
