Can I walk from the Beijing Express Train stop in Dongzhimen to the Forbidden City?

Oh, the distance between these two places is about 6 miles (10 kilometers). I'm afraid that it's a long way to walk. Thus you can take metro line 2 to Jianguomen Station and transfer to line 1 to Tiananmen East Station, Exit A. Afterwards, walk north around 0.6 miles to find the ticket office of the scenic area.
