For decades queer women in the Sinophone world have followed a strict dating custom: a lesbian relationship usually consists of a masculine partner, known as a tomboy, and a feminine counterpart. In the 2010s, however, many queer women have come to reject this custom and abandon their own former identities as tomboys. Leaving The Tomboy Behind follows their journey moving beyond lesbian masculinity and turning towards global LGBTQ+ media from Japan, Thailand, and the United States to explore new forms of gender expressions. Carman K. M. Fung offers a rich ethnography of the impacts media has had on queer Sinophone women’s lives, focusing on transnational interpretations and misinterpretations, and how media globalization shapes viewers’ perceptions of unfamiliar places. Through a combination of personal interviews and analysis of the global media these communities consume, Fung traces the genealogy of the tomboy identity in China, Hong Kong, and Taiwan in relation to global queer and trans cultures.
