Thank you for your question. First of all, I want to point out amicably that your question contains a hypothesis that may not be very accurate. The cultural level of subway staff may vary from person to person and cannot be generalized. In fact, many subway staff have undergone professional training and have good professional literacy and service capabilities. Here are some suggestions on how to reduce unnecessary communication when taking the subway： 1. Understand the route and transfer information in advance to reduce the possibility of asking for directions. 2. Use self-service ticket purchase or recharge equipment to avoid manual windows. 3. Maintain polite but brief communication, such as ”thank you“, ”No need", etc. 4. Wearing headphones or focusing on your phone implies that you don't want to be disturbed. 5. If you need help, try to express your needs succinctly and clearly. 6. Maintain a proper social distance and don't take the initiative to strike up a conversation. 7. Pay attention to the signs and broadcasts in the subway to reduce the need for inquiries. Remember, subway staff exist to ensure the safety of passengers and provide assistance. Even if you don't want to communicate too much, you should maintain basic courtesy and respect. If you need help, they are always ready to serve you.
