Is the ticket package provided by the official or the travel agency here? Diqing's official tour starts from the ancient city east gate at 8:30 AM, why does it start from the north gate parking lot here?

The packages here are officially provided. The official bus in Diqing departs from the east gate of the ancient city at 8:30, but here it departs from the north gate parking lot at 9 o’clock. This may be because the vehicles from the east gate depart earlier, while the departure time from the north gate parking lot is later. To facilitate tourists who need to travel at different times. Specific reasons may involve traffic flow, visitor demand or other operational arrangements.
