Ask a question, why is Jialing called Jialing? What's the origin? What do you mean?

Jialing River, formerly known as Langshui and Yushui, is the largest tributary of the Yangtze River system, named after it flows through the Jialing River Valley in the northeast of Fengxian County, Shaanxi Province. The headwaters of the upper reaches are Bailong River and Western Han River, and the lower reaches of Lianghekou in Lueyang County, Shaanxi Province are called Jialing River. Total length 1 1 19 km, drainage area160,000 km2, surpassing the Han River and ranking first among the tributaries of the Yangtze River.

The name of Jialing River is named according to the Water Classic Note: "The south (west) Hanshui River and Jialing River Road are Jialing River Water". This "Jialing Road" was set up in the Han Dynasty, which is equivalent to the current 1 county. It can be found in History of Han Geography that Emperor Wu of Han Dynasty added 28 counties, including Wudu County and 9 counties led by Wudu County, including Jialing Road. Instead of wine, there are Yu Zhi, Gansu Xintongzhi, Sichuan Tongzhi and so on. Jialing River is named after the Jialing River Valley which originated in the southwest of Dasanguan. According to Ma's Records of Jialing River, Dasanguan is located in the northeast of Dasanguan, not the source of the river, because the water in the north of the mountain is Weihe River, and there is no Jialing River valley in the southwest of Dasanguan. Inferring from praise, inclination and meridians, there is the name of "water" first, and then the name of "Tao". The author thinks that the name of Jialing River Road is the same, that is, Jialing River precedes Jialing River Road. This paper thinks that "Jialing River Road is the earliest road for people to pass through Guanzhong in ancient times", and the Water Classic Notes says: "The water flowing out of Zhoudao Valley is in the south of Gudao County, while the bronzes in the Western Zhou Dynasty are scattered.

As for the evolution of the name of Jialing River, according to the Atlas of China Historical Manuscripts edited by Guo Moruo, Jialing River was named Diving during the Warring States Period (475 BC-22 BC1year). Since then, from the Western Han Dynasty to the Tang Dynasty (206 BC-907 AD), the whole Jialing River from its source, Panjiashan, to Chaotianmen was called the Western Han River. According to Yuanhe, the name "Jialing River" has a history of 1000 years. Since the Tang Dynasty, Jialing River has been used to refer to the reach from Lueyang to Chaotianmen. Qing Jiaqing Tongzhi called Jialing River "Wenshui, Bashui and Yushui", and The Encyclopedia of China, Geography of China, thought that "water was called between Yushui and Wenshui in ancient times".
