Legal analysis: If college students are illegally detained by the administration, they can't go into politics, can't take an examination of civil servants, and it's hard to find a job. The public security organs of administrative detention will keep punishment files for a long time according to the regulations, so administrative detention will leave criminal records. And it will have a certain impact on the work. Of course, administrative detention is just a criminal offence, and the impact will not be great.

Legal basis: Article 53 of the Law of People's Republic of China (PRC) on the Prevention of Juvenile Delinquency. Minors who are detained, arrested or executed in juvenile reformatory should be detained, managed and educated separately from adults. Community correction of minors should be carried out separately from adults. Public security organs, people's procuratorates, people's courts and judicial administrative departments shall cooperate with the administrative departments of education to ensure that minors who have not completed compulsory education continue to receive compulsory education.
