If you want to take this route.
After arriving at Xuancheng Station, take a taxi to Xitouwan (Nongban Station towards Shuiyang, there are also shuttle taxis) and take a bus to Shuiyang. Then follow your route
But I recommend you take a bus to Jiuzhou Market Station, near the railway station, to Liqiao and take a bus directly from Liqiao to Gaochun! After all, there are more changes.
I hope to adopt it
