Hohhot was, in my experience, a dreadful city. Not much to do, nowhere decent to stay on the cheap, and really difficult to understand public transit system.
My one really positive memory from Hohhot was the 5 Tower Temple, which looks so stunningly NOT Chinese-Buddhist that I had to hang around for a while and stare at it.
My main memory, though, is the unfortunate distinction of Hohhot being the only city in China where I ever accidentally missed my train. The fact that it was a city I was very ready to leave made it that much more frustrating.
Sorry you did not enjoy the city & that you missed your train but it is a beautiful building & I simply enjoyed the picture.
