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.

Results show that 71.9 percent of the young couples have help from their parents in taking care of their kids.

Grown up as the "single-child", the only child in a family since the family planning policy was adopted in 1979, this generation depends much on their parents.

The parents of the "single-child" generation focused more on their children's physical well-being rather than their attitudes and values, according to some psychologists.

The research also found that the "double single-child couples" follow a rather traditional value system.

Survey shows that 27.5 percent of them got married after dating for one to two years, 25.2 percent two to five years, and 20 percent didn't tie the knot until dating for five years.Also, 30 percent of the couples were schoolmates, while 43.8 percent were introduced by someone.

Since their marriage are based on enduring relationships, 65.2 percent of the husbands and 62.9 percent of the wives think that compromise(妥协)and tolerance(宽容)are necessary in their marriage.Meanwhile, 21.7 percent of the husbands and 37.1 percent of the wives support the idea that happiness is the key standard for a marriage.
