I want to go to Dalian by train from Qinhuangdao. At which station should I get off?

At Dalian Railway Station. There is a big bus parking lot on the right front (that is, on the right side of the railway station square) after leaving the station. Take the trolley bus 10 1. (Tickets are not sold, coin is one yuan/person) Don't cross the road after getting off at Gaizhou Street (head west), turn right (north) and walk for about 3 minutes to Changping Primary School.
