Legal analysis: before suing for debt collection, creditors will apply to the court with jurisdiction to preserve the debtor's property. The purpose of this is to prevent the debtor from transferring the property privately in the course of litigation, and the creditor will not get the money after winning the case. If the applicant fails to bring a lawsuit or apply for arbitration according to law within 30 days after the people's court takes the preservation measures, the people's court shall lift the preservation.

Legal basis: Article 93 of the Civil Procedure Law of People's Republic of China (PRC), if an interested party fails to apply for property preservation immediately because of an emergency, which will cause irreparable damage to his legitimate rights and interests, he may apply to the people's court for property preservation measures before bringing a lawsuit. The applicant shall provide a guarantee. If no guarantee is provided, the application shall be rejected. After accepting the application, the people's court must make a ruling within 48 hours; Where property preservation measures are ordered, they shall be executed immediately. If the applicant does not bring a lawsuit within 15 days after the people's court takes the preservation measures, the people's court shall lift the property preservation.
