I want to go Jinan from Beijing international airport through bus. How to go please direct me?

No bus from the airport can take you to Jinan directly; you can go to Yongdingmen Long-distance Bus Station to take a long distance bus to Jinan. You can take shuttle bus line 10 to the south railway station, then walk to Yongdingmen Long Distance Bus Station and take bus there. There you can take bus to Jinan directly.
