Xialing broke stereotypes even behind the camera. https://t.co/soFfbltoHi— BuzzFeed (@BuzzFeed) September 13, 2021
Originally the character Xialing had a red streak in her hair. After reading a Teen Vogue article about the stereotype of female Asian characters sporting a red or purple streak to show their rebelliousness (and therefore their break from the "normal" meek Asian woman), Mang'er Zhang asked that it be changed.
They were already a month into shooting, but Marvel let them make the change, and they fixed previously shot footage in post.
