I used to go from Changning Branch Road of Jiangsu Road to Hutai Road Station of Shanghai Bus Express Passenger Transport Co., Ltd. ..
My route: Take the 923 bus to Yejiazhai Road (on Zhongshan North Road) and transfer to Bei 'an Line. It seems that I got off at Hutai Road Station. I forget it after a long time. When you get on the bus, you can ask the driver which stop is the nearest.
And 129.
From Wuning Road near Cao Yang Road, you can go to Ba Village, Cao Yang, and take Bei 'an Line.
I hope I can help.
