Legal analysis: it can not be eliminated. After a crime is sentenced, even if the sentence is completed and released, its criminal record will always be on file and will not be canceled. Eliminate the record of criminal responsibility in the file, that is, the so-called case file is basically impossible, only in individual places there are some relevant provisions and judicial interpretations, that can be a minor criminal behavior can be positively repentant can be sealed in the file of the criminal record, so the criminal case file will be accompanied by the person concerned for life. As long as it does not violate the law and does not affect life and work. If it is a minor offense, in employment, join the military, exempt from the obligation to report.

Legal basis: The Criminal Law of the People's Republic of China Article 100 A person who has received criminal punishment in accordance with the law shall, when enlisting in the armed forces or taking up employment, report truthfully to the unit concerned that he has received criminal punishment and shall not conceal it.

People who were under the age of eighteen at the time of committing a crime and were sentenced to less than five years' fixed-term imprisonment shall be exempted from the obligation to report as stipulated in the preceding paragraph.
