The public security organ can still find it, but it is generally not disclosed to the public
 The public security organ, the People's Procuratorate, the People's Court and the judicial administration organ are respectively responsible for accepting, examining and handling the sealing and inquiry of relevant criminal records within their respective functions and powers. The public security organ, the people's procuratorate, the people's court and the judicial administration organ shall affix the seal of "juvenile criminal record sealing" and other obvious marks on the cover of the criminal record file they seal, and store it separately or establish a special archive for sealing, and implement a special management and inquiry system. The public security organ, the People's Procuratorate, the People's Court and the judicial administration organ shall set the query authority in the relevant electronic information system, and shall not query the electronic information of the sealed criminal record without the approval and authorization of the legal query procedure.
 What is the process of querying juvenile crime files?
 The unit that needs to be inquired shall apply to the seal organ of minor crime records, stating the inquiry content, object, reason, etc. The organ for sealing criminal records reviews the inquiry application. If it meets the conditions, it will make a decision after discussion and issue the Notification of Consent to Inquiry of Juvenile Criminal Records. Finally, if the queried minor has no criminal record, or the inquiry subject does not meet the provisions of "special circumstances", the Notification of Inquiry Results of Juvenile Criminal Records shall be prepared for reply.
 To sum up, after a minor commits a crime and receives criminal punishment, the criminal record will be left, which will be filed by the judicial authority. If relevant information needs to be queried, it must be approved by the judicial authority, otherwise it will constitute an act of violating the privacy of minors. The judicial organ shall keep the criminal record properly. If someone divulges it, he or she shall be investigated for legal responsibility. I hope it is helpful to you. Criminal Procedure Law
 Article 275 If a person is under the age of 18 at the time of committing a crime and is sentenced to fixed-term imprisonment of not more than five years, the relevant criminal records shall be sealed up for safekeeping.
 If the criminal record is sealed up, it shall not be provided to any unit or individual, except that the judicial organ needs to handle the case or the relevant unit makes inquiries according to the state regulations. Units that make inquiries according to law shall keep confidential the sealed criminal records.
