So I think the best way is to take the so-called 70 1 bus, which is actually the airport bus. There is one stop to Qingdao North Bus Station, and the terminal to Haitian and Sifang Hotel. If you don't want to take a bus at North Station, go to Sifang Hotel opposite Qingdao Bus Station.
The only uncomfortable thing about this car is that it takes 15 yuan, one stop 15 yuan, and finally 15 yuan as soon as you get on the bus, but it's quite cost-effective compared with the taxi fare.
Another way to sit is to take the 305 bus. There are stops at Qingdao North Bus Station and Long-distance Station, but the speed is a word, so it is not recommended to take it.
