Weekend in the yellow mountains from Ningbo

Hello, my idea is to go during the weekend. The plan would be to stay one night on the top of the mountain and go back the next day.
Do you think is it possible? I see that the fastest way from Ningbo is the bullet train and it arrives around noon to the Huangshan city. We would like to go on the same day to see the sunrise and sleep there. The next day see the sunrise and go back to the train station because the train leaves at 15:40.
What do you think? I tried to find info about bus schedules but I couldn't.
