However, it can be seen that some procedures in the first and second trials are illegal, and there may be problems in the evidence to prove the facts of the case. You can continue to appeal to the Supreme People's Procuratorate and request the procuratorate to lodge a protest. There is no legal basis for the internal regulations of the procuratorate. If you do have conclusive evidence to prove that the judge perverted the law in the trial, you can also file a criminal lawsuit and ask the procuratorate to file a case, but it will be more difficult.
I suggest you send the judgment and relevant evidence, or you can entrust a lawyer to handle it directly.
