The route from Zhanjiang to Xiamen? Which is the most cost-effective? how much is it?

1. The plane, the plane doesn't go directly to Xiamen, so you have to take it in Sanya or Guangzhou, and the cost is relatively high

2. The train doesn't go directly to Xiamen, so you have to change to a bus

3. There is a bus that goes directly to Xiamen at Haitian Station, which seems to be the most convenient, so it is not so troublesome to change trains, and the driving time is about 16 hours
