How much is the bus ticket from Haikou to Shenzhen now? Where can I buy it to take away? How long will it take to sit there?

Go to Haikou West Station to buy tickets, or East Station. If you buy it at that station, take a bus at that station. You can ask the station staff if you have any questions. I won't know until I buy a ticket. Now the peak in Spring Festival travel rush has not passed, and it is estimated to be between 350 and 450. If you have time, it will take at least 14 hours to get to Shenzhen. It is better to buy a train ticket, which is cheaper. After taking the train from Haikou to Guangzhou (within 10 hour), take the Harmony high-speed train to Shenzhen (above 1 hour). All the tickets are estimated to be above 200. I wonder if there is a direct train to Shenzhen. Ask, maybe there is. . . .
