What bus will take me to hubei university of medicine from the airport?

As I know, your university is in Shiyan city. Is it the one you are referring to? If yes, take airport shuttle bus (Hankou line) to Jinjiadun Long-distance Bus Station. There you can take a direct bus to Shiyan Passenger Transportation Center. After that, you can take a taxi to the campus. Buses takes around 7h and they are scheduled at 09:50, 13:40, 17:30 and 19:00.

Thank you Bruce
