explanation: To have "arbitration", there must be "dispute", and to have "hearing", there must be "arbitration". To have a "trial", there must be a "litigation", and to have a "public gallery", there must be a "trial." there can be "macro control" without "inflation". To have "on-site rescue", there must be "emergency accident", and to have "aftercare" does not necessarily have to have "on-site rescue". The legal basis for guaranteeing "traffic safety" is "traffic laws", and "traffic safety" is not necessarily required to have "traffic laws".
