Legal basis:

Article 486 of the Supreme People's Court's Interpretation of Application

The people's court shall not dispose of the executed property unless it is sealed up, seized or frozen. For all kinds of property that can be directly deducted, such as bank deposits, the deduction ruling of the people's court also has the legal effect of freezing.

Article 487

The time limit for the people's court to freeze the bank deposits of the person subjected to execution shall not exceed one year, the time limit for sealing up or distraining movable property shall not exceed two years, and the time limit for sealing up immovable property and freezing other property rights shall not exceed three years.

if the executor applies for an extension of the time limit, the people's court shall go through the formalities for further sealing up, distraining and freezing before the expiration of the time limit for sealing up, distraining and freezing, and the time limit for further sealing up, distraining and freezing shall not exceed the time limit specified in the preceding paragraph.

the people's court may also handle the formalities of continued sealing up, seizure and freezing ex officio.
