Why are you talking nonsense upstairs? When Shishi arrives at Xiamen Airport, just go directly to Shishi coach station to buy tickets for Xiamen. There are two kinds: 1, Minnan Expressway and 35 yuan Expressway 1 hour 15 minutes. 2. The dedicated line Shishi-Xiamen 25 yuan takes the national highway for about 2 hours.
When you arrive in Xiamen, get off at Qian Dian Station (bus stop, make it clear to the driver) and then take a taxi to Gao Qi Airport, at most 15 yuan!
