I'm not sure where you are going. Guilin Medical College has a campus in Lequn Road and an Dongcheng campus in Qiaotou, Yushan. Lequn Campus is on Yiwu Road, not far from Guilin Library. 20 yuan can take a civil aviation bus out of the airport, either get off at Swan Hotel or get off at the Civil Aviation Building in the terminal building, and take a taxi around 15 yuan. Now the taxi fuel surcharge in Guilin is 2 yuan. If you want to go to Dongcheng Campus, get off at the terminal civil aviation building, and then take the No.32 road across the street and get off at Guilin Medical College Station.
