beijing airport subway line for panjiayuang market and silk market

1. To Panjiayuan Market: Take Airport Express to Dongzhimen Station and take subway line 2 to Chaoyangmen Station. Then take subway line 6 to Hujialou Station and line 10 to Panjiayuan Station, Exit B. Afterwards, walk southwest around 550 yards (500 meters).
2. To Silk Street: After arriving at Dongzhimen Station, take subway line 2 to Jianguomen Station, Exit B. Then walk east around 450 yards (410 meters).

thank you very much is a short time for going in a transport because i have only 12 ours in total?

Oh, for such a limited layover, public transportation would take too long and you may not be able to cover both of them. For your sake, I suggest you commute between and from/to airport to accelerate your travel and visit.
