How i can buy and collect ticket Shenzhen - Guilin?

You can buy the ticket online and choose to collect the paper ticket at the station counter after your arrival there. If you depart from HK for this trip, I suggest you to choose Lok Ma Chau instead of Lo Wu if possible. Lok Ma Chau is connected with Futian Port in Shenzhen side. It is a little easier for transfer. You can take subway Line 4 to Shenzhen north directly. It takes about 40min.
