Hi Gfreeze1,
I am not sure if I am getting your question right… I have been to BOTH mountains: Qingcheng Qianshan and Qingcheng Houshan… They are actually two different mountains. Qingcheng Qianshan (前山) refering to the “front” mountain – and not the “frontside” of the mountain… So “Qingcheng Houshan” is the Mountain behind “Qingcheng Qianshan“… Trying to walk (along the road) from the main entrance of the “front” mountain to the main entrance of the “back” mountain might take you 60 something minutes…
I think it is possible to spend the night at the top/near the top on both mountains – but I think the two mountains are not connected…
Hope this helps a bit…
