I want to ask how to find cheap dormitory in Huangshan? Not in the city, but in the mountains.

I checked Bei Hai Hotel and Xi Ai Hotel but I can't find cheap dormitory bed in their offer.
So if I will not find something cheap in the mountains to sleep is it worthy to start hiking in the morning and in the evening come back to the city and second day the same way? How long does it take to get from city to the Scenic Area?
