If the public security organ considers it necessary to arrest the detained person, it shall submit it to the people's procuratorate for examination and approval within 3 days after detention. Under special circumstances, with the approval of the person in charge of the public security organ at or above the county level, the time for submission for examination and approval may be extended by 1 to 4 days. With the approval of the person in charge of the public security organ at or above the county level, the time for reporting for examination and approval can be extended to 30 days for major criminal suspects who have committed crimes on the run, repeatedly committed crimes or committed crimes in partnership. The people's procuratorate shall, within 7 days after receiving the approval letter from the public security organ, make a decision on whether to approve or disapprove the arrest. If the people's procuratorate does not approve the arrest, the public security organ shall immediately release the suspect after receiving the notice and promptly notify the people's procuratorate to execute it. Those who need to continue the investigation and meet the conditions of obtaining a guarantor pending trial or residential surveillance shall be granted a guarantor pending trial or residential surveillance according to law. The people's procuratorate shall make a decision within 14 days if it deems it necessary to arrest a case directly accepted. Under special circumstances, the time for deciding to arrest may be extended 1 to 3 days. Those who do not need to be arrested shall be released immediately. If it is necessary to continue the investigation and meet the conditions of residential surveillance on bail, the bail or residential surveillance shall be lifted according to law. To sum up, in general, the longest detention period in criminal proceedings is 14 days. Major suspects who commit crimes on the run, commit crimes many times or commit crimes by gangs can be detained for up to 37 days. Because your question is more general, I suggest you call for advice, which is more direct and can better answer for you.
Legal objectivity:
For criminal detention decided by the public security organ according to law, the detention period is the sum of the time when the public security organ requests the people's procuratorate to approve the arrest and the time when the people's procuratorate examines and approves the arrest. This time limit = the time limit for submitting an arrest+the time limit for examining an arrest is 7 days. If the public security organ considers it necessary to arrest the detained person, it shall submit it to the people's procuratorate for examination and approval within 3 days after detention. Under special circumstances, with the approval of the person in charge of the public security organ at or above the county level, the time for submission for examination and approval may be extended by 1 to 4 days. With the approval of the person in charge of the public security organ at or above the county level, the time for reporting for examination and approval can be extended to 30 days for major criminal suspects who have committed crimes on the run, repeatedly committed crimes or committed crimes in partnership. The people's procuratorate shall, within 7 days after receiving the approval letter from the public security organ, make a decision on whether to approve or disapprove the arrest. If the people's procuratorate does not approve the arrest, the public security organ shall immediately release the suspect after receiving the notice and promptly notify the people's procuratorate to execute it.

To sum up, in general, the longest detention period in criminal proceedings is 14 days. Major suspects who commit crimes on the run, commit crimes many times or commit crimes by gangs can be detained for up to 37 days. The longest period of criminal detention is 37 days, and after detention, arrest is followed. If the circumstances are serious, they shall generally be sentenced to fixed-term imprisonment of not more than five years or criminal detention, and shall also be fined not less than/kloc-0 but not more than 5 times the illegal income.

According to Article 1 10 of the Regulations of the Ministry of Public Security, the crime of escaping refers to committing crimes continuously across cities and counties, or fleeing to other cities and counties to continue committing crimes after committing crimes at the place of residence; Multiple crimes refer to crimes committed more than three times; A partnership crime refers to a joint crime committed by two or more persons. If a criminal suspect and his legal representative, close relatives or lawyers entrusted by the criminal suspect think that the detention has exceeded the statutory time limit, they have the right to lodge a complaint with the public security organ or the people's procuratorate and demand that the detention be lifted. If the situation is true after examination, the criminal suspect and defendant shall be released. If the examination has not exceeded the statutory time limit, it shall give a written reply to the applicant. The difference between criminal detention and administrative detention is 1. Administrative detention is an administrative punishment measure. Criminal detention is a measure to monitor people who may commit criminal offences. Administrative detention can last up to 30 days, and it may also exceed 7 months. 2. Generally, violation of public security regulations or some provisions of civil law and administrative law will be punished by administrative detention, but if the act is suspected of a criminal offence, it will be turned into criminal detention. 3. Release people after the expiration of administrative detention punishment. If there is no crime in criminal detention, he will be released after investigation. The maximum period of criminal detention shall not exceed 37 days. If the circumstances are serious, they shall be sentenced to criminal detention or fixed-term imprisonment, with confiscation of property or a single fine.
