Depends on where you're going from, but you can't get there directly by subway either from the bus station or from the airport or train station. I'll talk about how to get there faster from all the important stops respectively, but I'm talking about public **** transportation, you don't need to think about that for a taxi.

Changsha bus station: 918 road and W204 road bus can be direct, both time is about the same, 918 from the nearby Yulan Road Chongyang intersection, Gautangling Avenue Wenyuan intersection under.W204 from Yulan Road Fenglin Road intersection, Gautangling Avenue Wenyuan intersection under.

Changsha bus station: 918 road and W204 road bus can be direct, both time is about the same, 918 from the nearby Yulan Road Chongyang intersection, Gautangling Avenue Wenyuan intersection under.

Changsha Railway Station: Take Metro Line 2 to Yingbin Intersection and transfer to Line 6 to Liugou ridge and then transfer to Line 4 and get off at Canziling. Then take bus W225 from the nearby Canziling East Station to Gaotangling Avenue and get off at Wenyuan Intersection.

Changsha South Railway Station (High Speed Rail): Take Metro Line 4 directly from the South Railway Station and get off at the terminal station, Jiansiling, then take Bus W225 from the nearby Jiansiling East Railway Station and get off at the intersection of Gaotangling Avenue and Wenyuan Road.

Huanghua Airport: Take Metro Line 6 directly to Wangchengpo (Changsha Bus Station West), and then take Bus No. 918 or W204 from the same station to Gaotangling Avenue Wenyuan Intersection.

I hope the above is helpful to you
