Hi, what is the fastest way to go Fragrant hill, if I start from Guloudajie (line 2) subway?

I read the reply before that it will be
Take Subway Line  2 to Xi Zhi Men | 西直门 and transfer to bus 360 to Fragrant hill (香山)

My question will be what exit should I take out of the mtr to the busstop? And is the busstop/ bus station right outside the mtr or if not can anyone tell me the direction to go to XiZhiMen busstation to catch bus 360? Thank you very much
