At present, judges are organized by the whole province and are found in all cities, forming a judge library. There is a computer drawing lots to decide who will go. The judges didn't know where to go until they got on the bus. After getting on the bus, they didn't know where to go until they handed in their mobile phones. After arriving at the hotel, the armed police are not allowed to go out on duty. In short, the current program design is reasonable, and there is almost no possibility of drilling holes.
It depends on your luck to improvise.
