The Qihe River Valley in Huairou is a peaceful place for nature lovers to get away from the busy city of Beijing. There, the noise and chaos of the city is decreased in this part of the city as Huairou is very far from the city center. The first thing you will observe here is the sound of water slowly running over stones on the drying river basin. Then the area will give you the laughter of kids catching fish with tiny nets, and the happiness of families enjoying the simple pleasures of nature filling the surrounding air with an amazing vibes of life.

Dear Hassan!
People who have been to Beijing said that it is difficult to drink clear and fresh water. They said that the water in Beijing is muddy because of the Yellow River and cannot be drunk. However, the water in the Qihe River Valley in Huairou is surprisingly clear. Do you think you can drink the water in the Qihe River?

Since ancient times, the Chinese people could not drink the water of the Yellow River, so they created artificial lakes and canals to purify the water of the Yellow River and make it drinkable.

The numerous artificial lakes and canals you've seen in Beijing were created to purify the muddy waters of the Yellow River.
