You go directly to Ryan bus station, right at the door. There are many scalpers at the door. If you have luggage, they will ask where you are going. The price to Xiamen Baisong Station is 170. As long as you agree on what time to arrive during the day, he will take you to the expressway by motorcycle. [Note: He won't ask you for a motorcycle again] Remember to give money to the scalper when you get on the bus, otherwise they won't take the initiative. Don't worry, both the driver and the scalper are involved. This was the case when I came to Xiamen last time. It will arrive in 6 or 7 hours; I hope you can come to Xiamen easily.
