Jin Zhejun a 33-year-old kindergarten employee, said there aren't any nursing rooms around her workplace in the city's Putuo district. She said she has to use a large towel to cover herself while she pumps breast milk in her office.

"It's embarrassing because there are male colleagues in the office," she said.

"I believe the app would make breastfeeding more convenient. But more important, companies and society should have more supportive measures for breastfeeding mothers," said Jin, who has an 18-month-old baby.

Meanwhile, Zhou Xinxin a 29-year-old mother in Wuhan, Hubei province, is leading a group of mothers who have gathered in online chat groups to draft a map of nursing rooms in every Chinese city.

Zhou, who encourages young mothers to find nursing rooms in their cities and report them to her, regularly releases the information through her Sina Weibo micro blog.

"An app like that would be very useful for breastfeeding mothers, but I hope it doesn't have any ads," Zhou said.
