How long does it usually take to sit for two years?

A criminal sentenced to two years' imprisonment should serve at least one year. Criminals sentenced to fixed-term imprisonment may have their sentences reduced if they consciously abide by prison regulations, receive education and reform, and truly show repentance or meritorious service during the execution period. After commutation of a fixed-term imprisonment, the actually executed term shall not be less than half of the original sentence.

According to the relevant laws and regulations, the time a criminal is held in a detention center should be included in the sentence (detention time in a detention center+sentence = fixed-term imprisonment) and sentenced to two years in prison. If you are not detained in a detention center, the actual sentence should be two years. As for whether the sentence can be reduced, it depends on the specific performance of the criminal himself during his sentence. Those who perform well or have rendered meritorious service may have their sentences reduced.
