Legal basis: Article 67 of the Criminal Law of People's Republic of China (PRC) voluntarily surrenders himself after committing a crime and truthfully confesses his crime. Criminals who surrender themselves may be given a lighter or mitigated punishment. Among them, if the crime is minor, the punishment may be exempted. If a criminal suspect, defendant or criminal serving a sentence who has taken compulsory measures truthfully confesses other crimes that have not been mastered by the judicial organs, he shall be deemed to have surrendered himself. Although the criminal suspect does not have the circumstances of surrender as stipulated in the preceding two paragraphs, he can be given a lighter punishment if he truthfully confesses his crime; By truthfully confessing one's crimes, particularly serious consequences are avoided and the punishment can be mitigated.
