Taking a taxi from the university town to the airport should cost about 140, because I used to take Shapingba from the airport and charged me 100 yuan. It usually takes 50 people to run from Shapingba to the university town. When we go to town or school, we have to take a bus, which is very convenient. If you go to town, you can take bus No.266 (Chongqing University starts and the terminal goes to Shapingba Normal College) or sit at the gate of the Academy of Sciences. I forgot the specific way, so it's better to take bus no.266. Personally, if you go to school from the airport, you can get a bowl of water by taking the airport bus.
