Today is Saturday, I don’t need to go to school, so I decided to take some morning exercises. Early in the morning, I went out of the house and looked around, the city was so quiet. With few cars, the air was fresh, I felt so comfortable. Besides the people who took the morning exercise, I found some people who worn the orange uniform, they were working. This was the first time for me to see the cleaners work in the morning, they were easily neglected, because they worked so early and when the time for people to go to work, cleaners rested. Watching these cleaners working, I feel so thankful for them, they were doing the greatest job. People praised them as the city’s dressers, they kept the city clean all the time and brought comfort to people. They are the respectable people, we should applause for them.
