Is there any direct train to teochew country side from Shenzhen railway station?

Do you refer to Chaozhou as your arrival city? If yes, no direct trains are running there from Shenzhen. But direct coaches are available and it costs around 4hrs.

You mean direct coach from Shenzhen railway station? Is it safe as 4 hours and robber case reported several times in the past. Anyway, I'll consider it as save time to there if safe. How much is the fare? How to buy the ticket and where to buy?

Thank you very much for info given.
