Beijing's legislators passed a new family planning regulation on Thursday, allowing remarried couples who have had two children to give birth to another child.

According to the new regulation, remarried couples who had one child before remarriage and then gave birth to a child after getting remarried are allowed to have a second child together. Moreover, if remarried people have two children or more before marriage and have had no child since remarrying, they can also give birth to a child together.

Previously, Beijing only allowed remarried couples with a total of one child from both previous and current marriages to give birth to another child.

"The policy should be supported, as it will benefit a lot of remarried couples in Beijing to have another child. However, it will not be promoted across the country, as different cities have different situations," Huang Wenzheng, a demographics expert and former assistant professor at Harvard University, told the Global Times.

Unlike Beijing, the local government in Nanjing, East China's Jiangsu Province stipulated four scenarios in which remarried couples will be allowed to have another child, including when the partner that is an only child has no offspring and his or her spouse already has two children.

Han Zhiyun, a 31-year-old woman who married a Beijing man who had previously fathered twins, told the Global Times, "I still feel that the policy discriminates against people like me, who married for the first time with someone who was married previously."

"Why can I not have two children with my husband like other couples?" she asked.

Han gave birth to a daughter in 2013, and under the previous family planning regulation, she could not get a Beijing household registration for her baby.

The new regulation also provides a 15-day vacation for husbands during their wives' pregnancy and extends female workers' maternity leave to 7 months.  Current national regulations allow women only 98 days of maternity leave.

Some additional rules and complications were also voided by the new regulation. For example, it scrapped a previous regulation stipulating that women are only allowed to give birth to a second child if they are age 28 or older or if it has been at least four years since the birth of their first child.
