Directions from Subway Line 5 to Mutianyu Great Wall section please. Thank you.

Take Metro Line 5 to Chongwenmen Station and then interchange to Metro Line 2 to Dongzhimen Station. After that, get out of the Exit E and walk northeast about 500m to take Bus Line 916 to Huairou North Avenue. Then transfer to Bus Line H23 or 7 to Xinying Station. Get off and you can see the Mutianyu Great Wall. It takes about 3 hours to finish the whole trip.

Thank you James for your response. I'll follow these directions.
Best wishes.
