The Huang Mountain is a place of interest. There are lots of tourists seeing sights every day. Years ago, some of them paid no attention to environment protection. They threw about waste paper, plastic bags and tins. Besides, they killed animals, caught birds, destroyed trees and flowers. Worse still, they often made a fire to cook in the forest. That was dangerous. Changes have taken place now. When tourists leave, they take away rubbish with them. They no longer hunt animals. Plants are also protected. All the tourists carry their lunch in order not to start forest fire. We must sing high praise of the good deeds.
