Three years ago, like many young people who went to big cities after graduation, Luo Mengjie, my girlfriend, defied the opposition of her family, and accompanied me longingly to get on the southbound train. It’s not easy for migrant workers to earn a living. Only those who have tasted the hard work know it. Born in a rich family, Mengjie has always been spoiled, but can not get used to the contrast of life. Fortunately, she loved me, and the intense feelings between men and women made her ignore these for a time, and did not bear too many complaints.
