No matter how late the flight is, there must be an airport bus. Take the airport bus for 45 minutes to the corner of the road, and then take a taxi to Northeastern University to dial the meter. There is no danger. If you don't carpool, remember to let the taxi hit the meter. The total cost is 15+ 10 = 25 yuan.

It is not recommended to take a taxi directly from the airport to Northeastern University, so at least 70 yuan is required at night.
