The specific solutions for transferring a large amount of foreign exchange into China to be frozen by the People's Bank of China are as follows:

You can take the initiative to go to the Interpol Brigade to cooperate with the investigation. After the criminal police confirm that the frozen deposits and remittances are really irrelevant to the case, the criminal police team will unfreeze the bank card, or you can wait for automatic unfreezing.

According to Article 229 of the Procedures for Handling Criminal Cases by Public Security Organs, the time limit for freezing deposits is six months. If it is necessary to extend the time limit for special reasons, it shall go through the formalities of continuing the freezing at the public security organ before the expiration of the freezing period. The maximum period of each freeze shall not exceed six months. Failing to go through the formalities of continuing to freeze within the time limit, it is deemed to be automatically unfrozen.
