There is a bus to Xiangtan in the square in front of Zhuzhou Railway Station, which seems to be 17 or 18. It takes about an hour to get to Xiangtan bus station. If you are a freshman, you can see the welcome point of Xiangtan University at Xiangtan Bus Station and take a free bus to Hunan University. (If you don't take the school bus, take bus No.6 and get off at the [South Gate of Xiangda University] station. )
The plane goes from Haikou to Changsha Huanghua Airport and directly takes the airport bus to Xiangtan, but it seems that there are fewer flights. If the ride time is not suitable, take the airport bus to Changsha, and then take a bus to Xiangtan at the bus station opposite Changsha Railway Station. The back is as above.
