Which bus should I take from Greentree Inn Dalian Development Zone to the railway station?

At Anshan Road Bus Station next to Green Tree Inn (Dalian Development Zone Store), take bus No.6 from Development Zone and get off at Jinma Express Railway Station, take Express Railway Line 3 (direction of Dalian Railway Station), get off at Jinma Road Station and get off at Dalian Railway Station. Dalian Railway Station is in the south of the station. The whole journey is more than 27 kilometers.
