When we 12 arrived in Dalian, the basic traffic was over. If we want to go downtown, we can only take a taxi. Drivers at night are not well protected, especially in terms of safety, so we suggest finding a place to live near the airport.
The red sun upstairs is ok, and there is also an air force guest house near the airport.
It takes about 30 ~ 35 ~ to take a taxi to the city center, that is, the train station.
Good luck. Safety comes first.
