Every day in the very early morning when most of us are still in our deep sleep, they start their work on the street, no matter it is hot summer or cold winter. Because of their hard work, our city which will otherwise be quiet dirty can be kept in a very clean condition,and as a result of which, we can live more comfortably. It is just because of them, our city becomes more and more beautiful, physically and even mentally.
As for all the cleaners, people may say they are small, but it is just the small work of them that makes a great difference to our life and environment. I respect from the bottom of my heart.
