The total length of the Yangtze River is approximately 6,397 kilometers; the total length of the Yellow River is approximately 5,464 kilometers.

Introduction to the two rivers:

The Yangtze River is the third largest river in the world and the largest river in China. Together with the Yellow River, Huaihe River, Haihe River, Pearl River, Songhua River and Liaohe River, it is collectively known as the seven major rivers in China. The Yangtze River originates from the southwest side of Geladandong Peak in the Tanggula Mountains of the Qinghai-Tibet Plateau. Its main stream flows through 11 provinces (autonomous regions and municipalities) including Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai. Shanghai Chongming Island flows into the East China Sea. The tributaries extend to eight provinces and autonomous regions: Guizhou, Gansu, Shaanxi, Henan, Guangxi, Guangdong, Zhejiang and Fujian. The Yangtze River basin covers an area of ??1.8 million square kilometers and the main stream is 6,397 kilometers long, ranking third in the world after the Nile River and the Amazon River.

The Yellow River is a large river in northern China, with a total length of approximately 5,464 kilometers and a drainage area of ??approximately 752,443 square kilometers. It is the fifth longest river in the world and the second longest river in China. The Yellow River originates from Maqu in the Yogu Zonglie Basin at the northern foot of the Bayan Har Mountains on the Qinghai-Tibet Plateau, in the shape of a "ji". From west to east, it flows through 9 provinces, cities and autonomous regions, including Qinghai, Sichuan, Gansu, Ningxia, Inner Mongolia, Shaanxi, Shanxi, Henan and Shandong, and finally flows into the Bohai Sea. The middle and upper reaches of the Yellow River are mainly mountainous, while the middle and lower reaches are mainly plains and hills. Because the middle section of the river flows through China's Loess Plateau, it carries a large amount of sediment, so it is also known as the river with the most sediment in the world. But in Chinese history, the diversion of the lower reaches of the Yellow River had a huge impact on human civilization. It is the most important birthplace of Chinese civilization and is called the "Mother River" by the Chinese. Nearly 1.6 billion tons of sediment are produced every year, of which 1.2 billion tons flow into the sea, and the remaining 400 million tons remain in the lower reaches of the Yellow River for many years, forming alluvial plains, which are conducive to planting.
