On the subway, the staff's communication is mostly to ensure the safety of passengers and smooth travel. If you want to reduce communication with them, you can take the following methods: 1. **Stay focused**: When riding the subway, you can focus on your phone, books or other matters, and avoid active eye contact or verbal communication with the staff. 2. **Simple response**: If the staff actively asks you relevant questions, you can respond with simple "OK" or "Thank you" to avoid starting a conversation. 3. **Learn information in advance**: Before taking the subway, learn about the routes, timetables and related precautions in advance to reduce the chances of asking questions to the staff. 4. **Use headphones**: Wearing headphones to listen to music or podcasts will make you appear more focused and reduce the chances of talking to others. 5. **Polite attitude**: If the staff communicates with you, you can maintain a polite but brief response to avoid in-depth communication. Through the above methods, you can effectively reduce unnecessary communication with the staff when riding the subway.
