But I remember it was sent from school to downtown at half past eight.
School-Qiaobei-Da Qiao South Road-Shaanxi Road-Dafang Lane-Yunnan Road-Xinjiekou
Basically, the teacher stops at the station where he gets off ~ if there is no teacher, it is likely that some stations will stop.
The school bus doesn't pick up people from downtown in the early morning ~ it's the Xinjiekou line ~ you can go back to school when you get on the bus at the terminal Xinjiekou ~ the school buses at other return stations are not obliged to stop to pick you up ~ and the time is not necessarily.
The school information announcement has the specific departure time of each line ~ if you don't believe it, you can search it.
