Want to know: Where is the watershed of Qinling Mountains in China?

The Qinling Mountains are an ancient east-west folded and faulted mountain range located in central China. It starts from the southern part of Gansu Province in the west, passes through the southwestern part of Shaanxi Province and ends in the western part of Henan Province. It is the watershed between the Wei River, a tributary of the Yellow River, and the Jialing River and Han River, tributaries of the Yangtze River. 1,100 kilometers long. The western section of the Qinling Mountains in Gansu has lower mountains, with peaks about 2,000 meters above sea level. There are Chengxian, Huixian and Liangdang basins sandwiched between the mountains. The East Qinling Mountains to the east of the upper reaches of the Jialing River run east-west, with tight folds, huge mountains, and narrow valleys, with an average altitude of about 2,000 to 3,000 meters. The main peak, Taibai Mountain, is 3,767 meters above sea level. It is one of the few peaks over 3,000 meters in eastern China. There are ancient glacier relics on the top of the mountain. In the Weihe Plain in the north of the Qinling Mountains, there is a large fault, which is a fault block structure that tilts to the north and tilts to the south. The main ridge is located on the north side, with a steep and short northern slope and a gentle and long southern slope. The water system is asymmetrical. There are many cross valleys in the mountains, which are important transportation routes between the north and the south. The Baocheng Railway passes through the mountains along the Jialing River Valley. The Qinling Mountains are the geographical dividing line between north and south in China. It has a significant blocking effect on air flow. In summer, the moist oceanic airflow cannot easily penetrate into the northwest, making the northern climate dry; in winter, it blocks the southward invasion of cold air, making the Hanzhong Basin and Sichuan Basin less susceptible to cold air. Therefore, the Qinling Mountains become the dividing line between the subtropical zone and the warm temperate zone. To the south of the Qinling Mountains, the rivers do not freeze, the vegetation is dominated by evergreen broad-leaved forests, and the soil is mostly acidic. To the north is the Loess Plateau, where the average temperature in January is below 0°C, the rivers freeze, the plants are mainly deciduous broad-leaved trees, and the soil is rich in calcium. The Qinling Mountains and the Bailongjiang River Basin still preserve contiguous forests and contain rare animals and plants. Foping is one of the places where giant pandas live. Walnuts from Shangluo area and angelica from Minxian County are both famous for their high yield and high quality. The broad Qinling Mountains include Xiqing Mountain, Min Mountain, Dieshan Mountain, Zhongnan Mountain, Huashan Mountain, Xiaoshan Mountain, Songshan Mountain, Funiu Mountain, etc.
