Directions for hiking Huanghuacheng Great Wall

The directions on the website are excellent except it does not explain what to do when we get off of the tourist bus. Can someone tell me where on the map of the Huanghuancheng Great Wall that is on your website I will be when I get off of the tourist bus? Also, does the tourist bus go back to Dongzheim at night? if so, do we catch it where we got off?
