A person in the park I always train kungfu near a shool in the morning . A middle-age man picks up rubbish around the school every day . He has been picking up rubbish for nearly ten years as I have been training my kungfu for almost ten years too. One day he told me about his job, smiling . NObody would like to pick up rubbish when the headmaster had a meeting to discuss But he would like to accept it and does it better . Most people dsilike the job and would look down on him .But he doesn't care what other people think of .A job is a job . He like nature and he would like to pick up the rubbish around th e school .It is duty to keep the clean schoolground . I am surprised at him . what a peaceful man ! I remember that Mao zhe dong had ever metioned that a person will face any difficutlies bravely if he could eat a root of grass . i think the person will live a happy life as he has a peaceful heart . in today's society .we need money ,but we also need more important things than money .I t is a peaceful and kind heart .and love the nature , love ourselves and others . would you like to tell me what you are thinking about when you look throught this writing ? Everyone has to deal with kinds of problems in life , Maybe someone will feel happier comparing to the person . hope everyone has a happy day !!
