I took the subway to Qingdao Station and then walked to Qingdao High-Speed Railway Station.

You can take Metro Line 3 from Qingdao Station and get directly to Qingdao High-speed Railway Station. Get off at Qingdao High-speed Railway Station, the terminal station of Metro Line 3, and you can reach Qingdao High-speed Railway Station after exiting the station. Please check the specific timetable and transfer information to ensure a smooth trip.
