Under GB/T 22485-2021, how should a taxi driver interact with an international passenger who does not speak Chinese?

1. Refuse carriage immediately because language barriers cause misunderstandings
2. Remain patient, use translation apps or standardized multilingual service cards, visually confirm the destination on a digital map, and strictly operate the taximeter
3. Charge an arbitrary foreign tourist premium of RMB 100
4. Take a long scenic detour assuming the passenger will not notice
