Which bus or train should I take from Dalian interntl airport to the university of technology?

By public transportation, here is the way: take subway line 2 to Jiaotong University. Then transfer to bus line 10 and get off at Luanjin Dongjie. Walk for around 500yd to the West Gate of the university. The school actually is only 13-14km from the airport, so you can also take a taxi for a direct travel. It costs CNY30-40 at most.
