Crystal Boys (孽子, pinyin: Nièzǐ, "sons of sin") is a novel written by author Pai Hsien-yung and first published in 1983 in Taiwan. In 1988, this novel went into circulation in China; its French and English translations were published in 1985 and 1989. A translation into German ("Treffpunkt Lotussee") appeared in 1995. Nièzǐ means literally "sinful sons" or "sons of sin", but it may also be an allusion to a passage in Mencius in which "friendless officials and concubine's sons" (孤臣孽子) reach positions of power because they have learned to live with a dangerous status.
