Go to Beijing Fragrant Hill from Dongdan Station. How do I get and what cost?

Dear Roger, you can take subway line 1 at Dongdan Station to Xidan. Then transfer to line 4 and get off at Beigongmen. Near the station, you may transfer to bus no. 563, which can directly take you to the park. The whole trip takes 60-70min and the fare is CNY7-8 per person.
