The article discusses how courts in China decide which court is responsible for handling a lawsuit. They consider two main factors: the level of the court and the location of the court. The level of the court is determined based on the type of case and the amount of money involved. The location of the court is usually where the defendant is located, unless there is an agreement stating otherwise. Sometimes, a higher court may take over a case from a lower court. In certain cases, parties cannot choose the court, and specific courts are designated to handle certain types of cases. Overall, Chinese courts have specific rules for deciding which court has jurisdiction over a case.
