What river is this?

The Luohe River, called Luoshui in ancient times, is one of the tributaries of the Yellow River. Originating at the southern foot of Huashan Mountain in Lantian County, Shaanxi Province, it flows through Luonan, Lushi and Luoyang and joins the Yellow River in Gongxian County. The total length is 467 kilometers, and the drainage area is1.5438+0,000 square kilometers. Luoyang basin is the largest basin in the basin, with a length of about 100 km from east to west and a width of 20 km from north to south, with fertile land and abundant water resources. It is one of the earliest areas where primitive agriculture originated in China. As early as seven or eight thousand years ago, there were grain planting and animal husbandry. Legend has it that water conservancy irrigation began in the Zhou Dynasty. Kaiyang Canal in the Eastern Han Dynasty turned Luo into Cao. Canal was built in the Sui Dynasty, and a large open channel was built in the Ming Dynasty, which continued to develop in the Qing Dynasty. Today's Luhun Reservoir and Guxian Reservoir are part of the Yellow River flood control project system. Luoyang, an important city in the river basin, is one of the seven ancient capitals in China, and it is a new industrial city with machinery manufacturing as its main industry. The river basin is also one of the birthplaces of Chinese culture, and many Neolithic cultural sites such as Mianchi Yangshao culture are widely distributed. According to records, the Luohe River Basin was the center of the Xia Dynasty (founded in 2 1 century BC). Erlitou, Yanshi, remains of Shang culture. The site of Xianxianggou Shang ancient city in Yanshi excavated in recent years may be Xibo, the capital of Shang Tang.
