Jinshanling tourist bus schedule

need clarification on jenny's answer regarding the tourist bus schedule.

The bus starts at 07:30 from Dongzhimen Bus Station and go back to Beijing at 14:30.

so, the bus would leave dongzhimen at 7:30, and arrives jinshanling around 9:30. and do you mean the bus will leave jinshanling at 14:30. or will it arrive dongzhimen at 14:30 (which means leaving jinshanling at 12:30)?
