A really nicely restored wall, similar in many respects to what there is at Xi'an but not so commercialized. It is lovely to walk around it or walk on it, and quite easy to find.

This little city is very different. It has on the surface a combination of different religions more so than other cities in china. It has Buddhism, Taoism, kong zi also. Its only 1 level high as all the dynasties before it have been flooded and its hasn't been rebuilt on like other cities. I think this element makes it amazing to go and see. You can take a rickshaw around town for 50-100rmb for a few hours and get the driver to take you to some nice local restaurants. Great for a few days.

The city wall is OK and you can climb up on it in certain places. West Gate for example has a small food museum (all in Chinese) housed in the gate house at the top and an open excavation of the previous gates that have stood there. The actual gate and wall section are heavily reconstructed and, even though it is quite nice, it is far too sanitized and new feeling. For 10 RMB, it's worth a look, but don't get too excited before you visit.
