The photo shows a dustman riding a motorcycle and holding a broom is smiling towards sunshine.The occupation of dustman symbolizes the meaning of labor,and he is smiling,thus conveying an idea that he loves his work,his duty,and everything in his life.It's such a positive attitude to hard but beautiful life that I was deeply touched and inspired.Besides,I guess he is going to go home after tiring work,reuniting with his family.It seems that he willingly accepts all hard thing in work while he is easily satisfied by little beauty in life,like clear sky,warm sunshine,and precious time after work.It deserves all people who always complain about life learning.
