According to the query on Lulin.com, the general period of freezing by criminal police in other places is six months. According to the "Procedural Regulations of Public Security Organs in Handling Criminal Cases", if the freezing period needs to be extended, the public security organs should go through the procedures for continuing the freezing before the expiration of the original freezing period. The maximum period of freezing renewal shall not exceed six months. For major or complex cases, with the approval of the person in charge of the public security organ at or above the level of a districted city, the period for freezing deposits, remittances, securities transaction settlement funds, futures margins and other property can be extended to one year, and the maximum period for each renewal period shall not be more than one year. The period for freezing bonds, stocks, fund shares and other securities is usually two years, and each renewal period shall not exceed two years. If there is no legal reason after expiration, and if it does constitute a criminal offense and the public security organs take criminal measures, the account will usually be automatically unblocked without the need to apply for unfreezing.
