In civil cases, it is generally to negotiate, authorize, investigate and collect evidence, write a complaint (or a defense), prosecute (or submit a defense and evidence), hold a court session, make a judgment and execute. If you appeal, you basically have to do it again. The time is uncertain. If the case is simple and the evidence is sufficient, the whole process from consultation to filing can be completed within 1 hour. If the case is complicated and the evidence is insufficient, all the evidence must be collected first. It's hard to say when.
In criminal cases, the complete procedure is to consult, meet with legal aid, get bail and wait for trial. Wait for the procuratorate to review the prosecution and defense, then investigate and collect evidence, write a defense, open a court session to defend, make a judgment, appeal, open a court session, make a judgment, and appeal, retrial, retrial if possible. The time is usually very long, and it is normal to delay for several years.
