You take 902 at the school gate and go to the west bus station.
Then go to the west bus station and take bus no.63, which is bus no.63, not bus no.603. Don't take the wrong bus.
No.66 bus is recommended not to take either. Although going to Changsha South Station, the speed is slow.
63 soon. It takes 55 minutes to get there.
Don't play too hard, at least 50.
