Transgender implies a person whose gender identity or gender expression differs from their assigned sex at birth. However, being transgender is not related to sexual orientation. Gender identity is defined as a sense of own gender. Instead of gender binary categorizing people as men or women, gender is interpreted as a spectrum including agender, genderfluid, pangender and etc. For gender expression, such terms focus on the cultural context on how people make use of their behaviors and manners, interest, make up and appearances to express their preferred gender roles. Cross-dresser, drag king/queen for examples. Regarding their gender identity and expression, traditional psychosis system tended to diagnose them as gender identity disorder which require forced treatment to rectify their preferences. Nowadays, the accuracy of such diagnosis and classification are being questioned. Such shift facilitates better diagnosis and adequate treatment for those who have mental illness ( 香港性文化學會 , 2017). On the other hand, transgender people can access proper psychological assessment for different level and types of medical intervention for sex change such as hormone therapy, sex reassignment therapy and other surgical reconstruction procedure (McCann & Sharek,2016). The terms "trans-masculine" means male who transitioned from female to male and "trans-feminine" means female who transitioned from male to female. Transgender people often being criticized and oppressed by traditional culture and religion. From they recognize their gender identity, “coming out” to their families and others, making changes from appearance to physical body, they bear great distress and negative emotions in such a rocky journey ( 莫坤菱 , 2018). Violence and unequal treatment from family, schools and workplace marginalized them socially and financially (White & Jaclyn, 2015). The society and government provide limited recognition and support for them. Having said that, LGBT social movement includes transgender community in the hope of raising more recognition and equal rights of transgender people. Transgender people should have their gender identity recognized without compulsory requirement of undergoing sex reassignment treatment. For example, the gender registered in identity card, equal rights for male/female as well as marriage ( 早安 , 2017).
