The Yellow River is the third longest river in Asia and the sixth longest in the world. The word “yellow” refers to the muddy water of it. The River，originating from Qinghai，flows through nine provinces, and finally pours into the Bohai Sea. It is one of several rivers for the Chinese to live on. “The river basin” is not only the birthplace of the ancient Chinese civilization，but also the most prosperous region in the early history of China. However, because of the frequent devastating floods, it has caused disasters many times. In the past few decades, the government has taken a variety of measures to prevent the disaster.
