In Hong Kong, detention centers play an important role in rehabilitating young offenders since their inception. Compared to industrialized countries in Europe, locking up young people in Hong Kong, who are first or second time offenders, is relatively common. Yet, the public is in the dark regarding the imprisoned youth’s life behind bars. To fill this void, this paper offers insight of the insider who volunteered to share his real life experience in a detention center. The paper is divided into four sections: (1) a glimpse into what a detention center is like using a young ex-offender’s own words; (2) the young ex-offender talks about how he spent his time in the detention center; (3) the young ex-offender examines whether detention had a constructive effect on his behavior 1 year after his release; and (4) thoughts are presented on the corrective programs for young offenders in custody.
