Which bus can I take to go from Chaoshan High-speed Train station to Chaozhou?

Which area do you refer to in CZ city? Do you refer to the area near by the Municipal Government? If yes, there is no direct bus that can take you to the destination. You need to transfer. And maybe the bus stops are not easy for you to find. So you can take a taxi to your destiona. This city is not a big. Taxi is a good transport for you.
If you want to go to the Municipal Government, the cab fare is CNY 30 to 40.
