Hi! How could I get from Longji Rice Terrace Scenic Spot to Sanjiang Train Station?

You can take a bus to Longsheng first (about 1.5 hours). Then, take transfer to a bus to SJ (about 1.5 hours). Upon arrival, take a taxi to the railway station for about CNY 10 (about 15 minutes). ;)

Hi, dear! The buses from Longsheng to SJ reach Hexi Passenger Transport Station. They are available from 6:30 to 18:00 at intervals of 30 minutes, and the duration is about 1.5 hours. Upon arrival, you can take a taxi or minivan to the railway station. ;)

Big thanks to both Samuel and Paco! Very helpful! The only thing is that the taxi actually was 50rmb (after 3 failed attempts this was the lowest rate I could get), maybe this is due to the poor road condition, and it took like 25-30mim from the town to the railway station.
