A Beautiful Natural Place I Visited
Last year I visited Jiuzhaigou Valley in Sichuan Province. It's a beautiful valley with colorful lakes and waterfalls. The water is so clear that you can see the bottom. Many trees surround the lakes, making the scenery like a painting.
I like this place because the air is fresh and the environment is peaceful. The most impressive thing was the Five-Color Pond, whose water shows different colors. I took many photos there. It's really a wonderful gift from nature.
