《孽子》是台湾作家白先勇在20世纪七八十年代创作的一部同性恋题材的长篇小说，主要讲述了一群被家庭和学校抛弃的少年聚集在台北的新公园里，在杨教头的领导下组织成了一个非法的地下同性恋王国。《孽子》自出版以来，在海内外获得的评价呈现了一种从冷变热的逐渐演变的过程。通过研究发现，《孽子》的评价史可以分为三个时期：可有可无的同性恋框架、呼吁宽容与理解、自我认同和社会认同。同性恋一直是争论《孽子》的焦点，但我们也发现，对《孽子》的研究中，同性恋主题过分凸显，呈现出单方面的多元化。

Crystal Boys is a novel about homosexuality written by Taiwan writer Xianyong Bai in the 1970s and 1980s. It centers on a group of teenagers abandoned by their families and schools who gather in the New Park in Taipei and organize an illegal underground gay kingdom under the leadership of coach Yang. Crystal Boys since its publication, first met with a cold reception, then more and more comments. It is found that the evaluation history of Crystal Boys can be divided into three periods: the dispensable framework of homosexuality, the appeal for tolerance and understanding, self-identity and social identity.Homosexuality has always been the focus of the debate on Crystal Boys, but we also find that in the study of Crystal Boys, the theme of homosexuality is overemphasized, showing a unilateral diversity.
