A new project was launched in 2016 and the local government invited Gunnarsson to create new pictures, with citizens volunteering as models.
In one of the previous posters, a man could be seen teaching his son how to play golf as his wife looked on. The same family was featured in Gunnarsson's version but this time around the wife was bowling while the husband acted as a cheerleader.
Gunnarsson also photographed a same-sex couple who married in 2009 after same-sex marriage was legalized in the country. Transgender individuals were also featured.
The photographer also sought to challenge the norm that children should pick up sports according to their gender. In an image of a pair of twin sisters, one is seen with long hair, dressed in pink and practicing ballet. In contrast, the other sister dons darker clothing, has short hair and prefers playing football and hockey.
The exhibition in China also features stories of six Chinese who have shared their views on gender equality.
One of these individuals is Zhu Linken, a nurse in Melbourne, who says while women are usually regarded as the best choice for nurses, men also have their advantages in this profession.
"Men are more adept at technical operations. They can be more rational during emergencies as well," says Zhu.
Yan Xiao, a designer from Hubei province's Jingzhou, says he joined a chat group on Chinese app WeChat when his daughter was born to learn more about topics related to raising a child. He is currently the only male in the group.
Yan says he once encouraged his daughter to help change the world when she grows up. But his wife thought that this was too much responsibility to bear for a girl.
"I asked my wife if her response would be different if we had a boy instead and she said such responsibilities should fall on men. So, you see, there is already a force limiting a woman's potential in society. This is why we need gender equality," he says.
According to the exhibition curator He Yining, a series of photo booth sessions, a talk on stereotypes of men and women in media and a film screening will also be held to provide the audience with a greater understanding of gender diversity.
