If you are dissatisfied at the second instance, you can apply for appeal to the People's Procuratorate where the court of first instance is located. After receiving the complaint, the Procuratorate will decide within seven days whether to file the case. After the case is filed, the Procuratorate will investigate the case.
At present, the court's handling of civil case complaints is based on the principle of filing a case, that is, filing a case first and then investigating, and filing a case as long as there is an application. However, the application does not stop the execution of the effective judgment.
