The widest part of the Yangtze River is the estuary, which is 180 kilometers wide, and the narrowest part is the Tiger Leaping Gorge in the upper reaches, which is less than 50 meters wide. Locals describe it as a tiger that can jump over, so it is called Tiger Leaping Gorge.

The widest part of the Yellow River is 1,500 meters, and the narrowest part is 300 meters.

Extended information

1. The Yangtze River

The long source is the southwest side of the Geladandong Peak of the Tanggula Mountains on the Qinghai-Tibet Plateau, the "Roof of the World".

The main stream flows through 11 provincial administrative regions (eight provinces, two cities and one district) including Qinghai Province, Tibet Autonomous Region, Sichuan Province, Yunnan Province, Chongqing City, Hubei Province, Hunan Province, Jiangxi Province, Anhui Province, Jiangsu Province, and Shanghai, and flows into the East China Sea east of Chongming Island, with a total length of more than 6,300 kilometers.

It is more than 800 kilometers longer than the Yellow River. Among the world's great rivers, it ranks third in length, second only to the Nile River in Africa and the Amazon River in South America. However, the Nile River basin spans 9 African countries, the Amazon River basin spans 7 South American countries, and the Yangtze River is unique to China.

The main stream of the Yangtze River runs across central China from west to east. Hundreds of tributaries converge from north to south, extending to parts of eight provinces and autonomous regions including Guizhou, Gansu, Shaanxi, Henan, Guangxi, Guangdong, Zhejiang, and Fujian.

The basin area is 1.8 million square kilometers, accounting for about one-fifth of China's total land area. Most of the water from the Huaihe River also flows into the Yangtze River through the Grand Canal.

The upper reaches of the Yangtze River above Yichang are 4,504 kilometers long, with a basin area of ​​1 million square kilometers. Among them, the section from Zhimen to Yibin is called the Jinsha River, which is 3,464 kilometers long. The section from Yibin to Yichang is commonly known as the Sichuan River, which is 1,040 kilometers long.

The middle reaches of the Yellow River are from Yichang to Hukou, 955 kilometers long, with a drainage area of ​​680,000 square kilometers. The lower reaches are below Hukou, 938 kilometers long, with a drainage area of ​​120,000 square kilometers.

2. Yellow River

Yellow River (China's second longest river)

The Yellow River is a major river in northern China, with a total length of about 5,464 kilometers and a drainage area of ​​about 752,443 square kilometers. It is one of the longest rivers in the world and the second longest river in China.

The northern source of the Yellow River originates from Zhaqu at the southern foot of the Chahasila Mountain, a branch of the Bayankala Mountains on the Qinghai-Tibet Plateau in Qinghai Province. The southern source originates from Kariqu at the northern foot of the Gezigeya Mountain, a branch of the Bayankala Mountains. The western source originates from Yugu Zongliequ at the west of Xingxiuhai.

It is in the shape of a "J" character, flowing from west to east through nine provinces (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. Since the middle section of the river flows through the Loess Plateau of China, it carries a lot of sediment, so it is also known as the river with the most sediment in the world. However, in Chinese history, the diversion of the lower reaches of the Yellow River has had a huge impact on human civilization.

The Yellow River is the main birthplace of Chinese civilization, and the Chinese call it the "Mother River". Every year, 1.6 billion tons of sediment are produced, 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 an alluvial plain, which is conducive to planting
