What's station number of Badaling Great Wall cable car in return trip?

From website info, if we choose to take a round trip of cable car (CNY60), it will take us to No.8 North Tower.
- When we arrive station no.8, which way we should walk to? From station no.8 to no.7 right?
- What's station we can take the cable car back in return trip? (We want to back to Badaling station to get a bus to Dengshenmen)

Thanks in advance.
