Pure tourism. Shopping such as you have never seen, for every taste, as well as a bit of history (check out the well). The best part by far, though, is the little street just off of it (the entrance may be immersed in steam as you walk through) filled with the best food you can get downtown (in my humble opinion, of course). There is nothing you cannot get on a stick, from squid to scorpion to silkworm, and there’s no better place to try some 羊头白水.
