I want to take subway from capital airport to Zhu Shi Kou subway station please advise

Well, there is no direct subway that can take you to the destination.
So you are suggested to take airport shuttle bus line 7, get off at South Gate of Qianmen Street. The ticket fare is CNY 24 per person. Then walk west along Zhushikou West Street around 330 yards to find the metro station.

But if you stick to take subways, take airport express to Dongzhimen Station first. Then take subway line 2 to Chongwenmen Station and take line 5 to Ciqikou Station. After that, take line 7 to Zhushikou Metro Station.
