Option 2: Take the ordinary airport bus (15 yuan) and get off at Shangqing Temple \ Guanyin Bridge, and then transfer to Bus No.462 to Shapingba. If you want to go to Guanyin Bridge, you can take bus No.863 or 18 1 (2 yuan), which is also under Shayang Road. You should ask Shangqing Temple.
The third option, luxury, takes a taxi directly to the B area of Chongqing University on Shayang Road after leaving the airport, but this is very expensive, about 70 yuan.
In addition, it is suggested that the road at two o'clock in Chongqing is very detour. After getting off the bus, you'd better ask the location of the old man station in the street. Otherwise it's easy to faint.
In addition, there are many antelope taxi drivers soliciting customers not far from the airport. It's best not to take a taxi. It's usually dark.
The teachers in the School of Architecture of Chongqing University are all very individual, but they are all competent. I wish you success in your studies!
