What's the most economical transportation (return trip) from Chaozhou to Guilin?

Hi there! There is no through train from Guilin to Chaozhou. I suggest you take a high speed train at Guilin West Railway Station or North Railway Station to Guangzhou South Railway Station first, then transfer to another train to Chaoshan. The return way can be the same. In addition, if you are traveling in slack season, you may consider the direct flight, for which you may get great rebate.
