Although progress has been made, equality between male and female professionals remains a critical issue in China.

According to a survey released by global recruitment specialist group Hays on Tuesday, women are less likely than their male co-workers to believe that pay equality and equal opportunities exist for both genders in the workplace.

Hays polled 521 professionals in China, 55 percent of whom were female. Only 7 percent of women aged 25 or under think there is gender inequality of pay. But as they progress in their career, that number increases. About 29 percent of women aged between 26 and 40, and 35 percent of women aged 41 or above think there is gender inequality of pay.
