Nowadays, child-bearing is losing its appeal for many young couples in big cities. Young couples put off having children or decide not to have on at all. We may have got different opinions about dink families. Many people think that competition is too fierce in the society, and raising a child takes up too much time and energy. They demand for self-fulfillment in their career, and they desire for their own freedom and happiness of a childless life. Of course, financial burden maybe is another reason. Some people even think dink family is modern and romantic, and it is the progress of our society. So they prefer not to have their child.
