There is also the latest Guangzhou to Chenghai. How can I take a bus? Is there a cheap direct bus?

Chenghai belongs to Shantou City, and Guangzhou has a train to Shantou. There is a shuttle bus to Chenghai after getting off the train. The train starts from Guangzhou South, the fare is 2 16.5 yuan, and it takes three hours to reach Shantou. If you don't want to reverse, you can take the intercity bus directly to Chenghai. From Guangzhou to Chenghai, there are four trips a day, with an interval of two hours, which takes five and a half hours. Ticket price 120 yuan. See the table below for the specific timetable!

Comparatively speaking, intercity bus is cheaper and there is no need to transfer.
