Hello 阿忠 ā zhōng,
When you are traveling in a foreign city and need help:
"Can you recommend a good restaurant around here?"
" How do I get to ......... ( a certain place) from here?"
" Do I have to change trains?"
"How much is the ticket?"
"Is this the only bus station in the city?"
" Do you have a schedule I could look at ?"
" Are there any buses going to ...... today?"
" What time does the Museum open (close) today?"
