The Yangtze River
The Yangtze River is the longest river in Asia and it’s also the third longest river in the world.
It is about 6,300 kilometres long. It starts from Qinghai Province and goes into the Pacific Ocean. There are many kinds of fishes in the river and some of them are endangered species.
People love the Yangtze River, but it is now polluted. We should try our best to protect it as it is very important for China. We should stop throwing rubbish and pouring waste water into it.
I hope it will become more and more beautiful.
