Explanation: In the movie Mulan the strong gender role involving men was prevalent, since back in those time periods, men were seen to have more power and a stronger mindset and ability than women and girls. It was a cultural norm for the men to lead and be seen as the dominant figures.
The most shocking gender roles were: women and girls being used to keep silence and not interfere with the men and issues, such as how Mulan was told to stay silent when her father was asked to join the army. Another is how women were to be killed if they were to join the army, and how men were only trusted throughout the movie.
It is different from our own culture in the U.S. since nowadays in today's society, both women and men are taken into notice and treated somewhat equally.
