when the railway station comes out of the platform, there is a 219 (turn Li) bus at the exit of the bus station on the right side. The fare is 2 yuan. The bus stops at 8:00 p.m. and then gets off at Xinjian County Magistrate. It takes about half an hour to get to the station. After getting off, there is an intersection ahead. Turn right and walk 100 meters to the opposite platform of the business school, The last bus of 509 is 6 o'clock.
if you can't catch the time, I suggest that you take a taxi of 24 yuan from the railway station to Xinjian County Magistrate, and then get off at the intersection mentioned just now. (there are many small vans nearby, private, not public transport. In order to earn some money, the local people are more secure, It's available before 10 p.m., 4 yuan for one person, 25-30 yuan for chartered bus.
