How do I get from Xiamen to Cha'an, please? Which mode of tranport can I take & cost?

Hi, R Chan.
Would you mind confirm the position, Cha'an? I did not hear it before.

So sorry. It's Chao'an. Also, how can I get from Shantou to Chao'an? Thank you.

From XM, there is no direct bus for Chao'an, so you need to transfer at Meizhou and then Chaozhou city.
From the XM, you can find direct trains to Meizhou and from Meizhou Bus Station, there are direct buses for Chaozhou city. From Chaozhou, frequent buses can be found to Chaoan.
Where are you in Shantou city? Generally speaking, the Shantou city bus line 7 can take you from Xiaogongyuan Bus Stop to Chaoan Bus Station directly.
