The Yangtze River, also known as Chang Jiang in Chinese, is the longest river in Asia and the third longest in the world. Its length is about 6,300 kilometers and it runs from the Tibetan Plateau in western China to the East China Sea near Shanghai.

The pronunciation of Chang Jiang is 'chahng jyahng' in Mandarin Chinese. The first syllable 'chang' rhymes with 'song' and the second syllable 'jiang' sounds like 'jung' with a soft 'g' sound.

The name Chang Jiang means 'long river' in Chinese, which is a fitting name considering its length and importance to China's history and culture. The river has been a vital transportation route for centuries and has played a significant role in China's economic development. It is also home to many species of plants and animals, including the rare Yangtze River dolphin, which unfortunately is now critically endangered.

Overall, the Yangtze River (Chang Jiang) is a fascinating and important natural wonder that has shaped the history and culture of China for thousands of years.
