                         The passengers cover the nose to avoid 
                          strong odor when passing Maoniu River.

                      | Since then people start to pour daily rubbish 
                        and industrial waste water from chemical factory and mill 
                        directly into the river, which leads to large amount of 
                        fish's death. The offensive odor in the river drives away 
                        passengers. What's worse, the environment of Maoniu River 
                        is completely out of control. |
