The Yellow River is a clear river in the upper reaches. For thousands of years, most people living here are ethnic minorities. Among them, mainly Tibetans evolved from ancient ethnic groups such as Qiang nationality. According to the topography of the upper reaches of the Yellow River, they named the upper reaches of the Yellow River with distinctive names, such as Kariqu, Yuegu Zonglie, Zhaqu, Xingsuhai, Maqu, Yan Zhi, Hequ, Jiuqu and Liu Feng Dahe. In Tibetan, this river is called Qu.
Analysis of Zhi, Hequ and Jiuqu
Analysis (giving) branch, Hequ and Jiuqu are the names of the upper reaches of the Yellow River in Han and Tang Dynasties and the reaches above Guide in Qinghai today. According to the Biography of Western Qiang in the Later Han Dynasty, "the shore is supported by branches, and as for the river head, it stretches for thousands of miles. The giver "Yugong" is also known as an analyst. According to Sang Qin's Notes on Water Classics and River II in the Han Dynasty, "Sima Biao said: Xiqiang is in the west of the branch, close to the river head, and the river bends to the northeast, and the diameter is in the place of analysis, which is used for meandering. Ying Shao said: Gong Yu's analysis branch belongs to Yongzhou, which is thousands of miles to the west of Heguan. Qiang people live there and are called Hequ Qiang. " According to the above ancient records, its geographical location is at the bend of the Yellow River in Hehe, Guinan, Xinghai, Tongde and Jiuzhi counties west of Guide County, Qinghai Province. Here, the Yellow River forms an S-shaped big bay in the southeast, north China, northwest, southwest and northeast, which is called "Laga-Guide River Bend". Because Guide set up Heguan County in the second year of Emperor Xuandi in the Western Han Dynasty (60 BC), which means to lock water (because the county is at the end of Longyang Gorge), it was called "Branch River" or "Hequ" in the Han Dynasty. This section of the Yellow River was also called "Nine Songs" in the Tang Dynasty. In the fourth year of Jinglong in Tang Zhongzong (AD 7 10), because Princess Jincheng of the Tang Dynasty married Tubo, the court designated the Jiuqu Land of the Yellow River (now Ledu, Qinghai), which is more than 600 miles southwest of Shaanxi Province, as the land of Princess Tom of Jincheng (A Brief History of Qinghai). There are many hot springs along the Yellow River in Guide and other places, which are suitable for bathing. As the saying goes, "The Yellow River has nine bends and eighteen bays in the world". This "nine bends" is the section of the Yellow River above Guide in the Tang Dynasty.
