The first one I can think of is Yangtze river, the third longest river in the world, and the longest in Asia. I don’t know exACTly how long it is, but I think it’s about 6000 kilometers or something.

　　Honestly, I don’t know what it looks like. I’ve never seen it in person. But there’s a branch called Xiang river which lies here in Changsha. Every evening, you could see many local residents taking a stroll, fishing or just chilling on the river bank.

　　As for why I think it’s important, well, firstly, Yangtze river contains an enormous amount of water power. Have you ever heard of the Three Gorges Dam? It’s a power plant built on Yangtze river which generates electricity for the southern cities in China using hydro power. It’s extremely important because it’s a sustainable way to produce electricity and to cut down the consumption of fossil fuels which causes damage to the environment. Now, the Three Gorges Dam has also become a must-go for tourists.

　　Moreover, in history, it was used not only for daily water use, but also irrigation, agriculture and transportation, which explains why it’s like a symbol of our country.
