1/ can I use the same China visa to exit at shen zhen as I know there is a different visa to enter Shen Zhen than Guangzhou?
2/ the trains from Guangzhou to Shenzhen (louhu)
-what train station do they leave from?
-do I need English to purchase a ticket?
-are there classes of seats?
-can I just turn up and will there be heaps going rather than booking?
thanks for your replies
