Save money: take a bus from the airport to 2 yuan, the North Bus Station (15 minutes), take a bus from Chengyang to 20 yuan, the long-distance station of the Development Zone (1 hour, take the Jiaozhou Bay Expressway), and then go west a little to the Petroleum University. It won't reach 30 yuan.

There is a more economical way to take a ferry, but it costs more 1 hour.
