I think some people misunderstand the Chinese parenting style,just like some Chinese misunderstand the Western parenting model. Both approaches emphasize one aspect,and so they each reach a certain extreme.In my opinion, the Chinese parenting style is not just about strictness or rigidity,nor is Western parenting just about freedom,which may ultimately lead to indulgence.展开更多

Or three whole years? Though Chinese laws and regulations allow 98 days of maternity leave, Zhang Lihui, a member of the 12th National Committee of the Chinese People's Political Consultative Conference, suggested that the entitlement be increased to three years, until the newborns are old enough to be sent to kindergarten. According to Zhang, this would not only meet the psychological and educational needs of children, but also help mothers work more efficiently in the future as they do not need to worry too much about their children.展开更多
