There are school buses between campuses, but the time is fixed and they are all early. You can take the bullet train from Quanzhou and get off at Jimei in Xiamen. Jimei is close to Gao Qi Airport, so taking a taxi is the starting fee.
In addition, there are two stops in Quanzhou that have buses to Xiamen, but that one is in Xiamen, which is still a long way from the airport. You need to take a taxi ~ some will stop at the airport, but just ask. .
