Hi there...
could you tell me how to go from Zhuhai to Guangzhou?
1. I am thinking of bullet train. What is the station name in Zhuhai?
2. What is the operation hour and how long does it take to reach Guangzhou?
3. Once I reach Guangzhou, what is the station name in Guangzhou?
4. What is the closest (walking distance) to the subway in Guangzhou?
thank you very much.
