Over 70 percent of the "double single-child couples" in China need help from their parents in taking care of their own kids, according to a recent survey．

"Women of China" magazine and a consulting company carried out a survey recently on young couples of the "single-child" generation, the Morning Post reports．The couples surveyed were around 29 and have been married for three years on average, with university education and monthly income of 4．000 yuan ($531)．Among them, 43．5 percent have kids．
