Gender Fluid is a gender identity best described as a dynamic mix of boy and girl. A person who is Gender Fluid may always feel like a mix of the two traditional genders, but may feel more boy some days, and more girl other days. 

“流性人”就是指性别在男女之间“流动转变”的性别认同。流性人也许经常会觉得自己是两种传统性别的混合体，但有时觉得自己更男性化，有时又觉得自己更女性化。

Being Gender Fluid has nothing to do with which set of genitalia one has, nor their sexual orientation. 

“流行人”与拥有什么样的生理特征没有关系。与他们的性取向也无关。
