I have to transit in Qingdao Liuting Airport from 11am till my next flight at 6pm.

Yes, you can make full use of your transit time and tour around downtown area. About the transportation, you can take shuttle bus no.702 to get to the Main Railway Station first. Then transfer to metro line 3 to Wusi Square Station, Exit D. After arriving, walk southeast around 750 yards to find the square. The return way is the same. Notably, remember to go back to the airport at least 2 hours in advance before the departure.

Thank you.
