Changchun national defense education base is in the suburbs, which is far from the urban area. You need to reverse to get there. If you have enough money, I suggest you get off and take a taxi. You should get off at Kaixuan Road Bus Terminal, which is near the north exit of Changchun Station. After you get off the bus, you have to go through the north-south underground passage of Changchun Station. Go to the south exit of Changchun, which is in front of Changchun Station. You can take bus, take bus No.62, No.362 or No.361and get off at Sanma Road, where you can take bus No.01,which is a suburban line. Coach is a mode of operation, with a conductor. Tell the driver or conductor to go to the national defense education base after getting on the bus. I hope my answer can help you.
