You can go to Quzhou Railway Station to take the bullet trains to SH South Railway Station and then take the same shuttle bus to go back. Or you can go to the Quzhou South Bus Station to take the bus to reach SH South Bus Station, which is near to the railway station and then take the shuttle bus line 7 to reach the airport.
For the back way, you can take the same routes to to back.
