How to determine that an act violates two crimes?

Legal analysis: According to China's criminal law, if the same crime causes several different crimes, the principle of combined punishment for several crimes shall apply. Several crimes must be committed within the statutory time limit. According to the provisions of China's criminal law, if the actor is found guilty of several crimes before the execution of the penalty, he should be punished for several crimes. If a criminal lawyer's defense judgment declares that a person has committed several crimes before, in addition to the death penalty and life imprisonment, the execution period shall be decided as appropriate, but it shall not exceed the total sentence or the maximum sentence among several sentences. If, after the judgment is pronounced, but before the execution of the punishment is completed, it is found that the sentenced criminal has committed other crimes that were not declared before the judgment was pronounced, a judgment shall be made on the newly discovered crime and the punishment to be executed shall be decided in accordance with the provisions of Article 69 of the Criminal Law. The executed sentence shall be included in the sentence of the new judgment. If a sentenced criminal commits another crime after the verdict is pronounced and before the punishment is completed, he shall make a judgment on the new crime and decide the punishment to be executed in accordance with the provisions of Article 69 of the Criminal Law.

Legal basis: Article 69 of the Criminal Law of People's Republic of China (PRC) declares: Except for those who have committed several crimes before, the execution period shall be decided as appropriate, but the maximum public surveillance shall not exceed three years, criminal detention shall not exceed one year, fixed-term imprisonment shall not exceed twenty years and fixed-term imprisonment shall not exceed twenty-five years.

Whoever is sentenced to fixed-term imprisonment or criminal detention for several crimes shall be sentenced to fixed-term imprisonment. Some crimes are sentenced to fixed-term imprisonment and public surveillance, or criminal detention and public surveillance. After the execution of fixed-term imprisonment or criminal detention, public surveillance must still be carried out.

If several crimes are combined, the additional punishment must still be executed. Among them, those with the same kind of supplementary punishment shall be executed jointly, and those with different kinds shall be executed separately.
