I like to go Xiaman from Guangzhou. Tell me the way by train and by air.

If by train, you can take train from Guangzhou East Railway Station. There are two trains running to XM each day, one in 19:34, another in 20:45. The train would take 12 – 14 hours. It cost CNY351 for the soft sleeper seat and CNY230 for the hard sleeper seat.
If by air, you will fly from Guangzhou Baiyun airport to Gaoqi airport. It would take 1 hour and 20min.

Thanks Dear
