China doesn't have a lot of old intact structures though since they used worse building materials than Romans. Age of the city doesn't matter much if all structures are new.

And no, the great wall of China isn't ancient. The parts we see today were built in the 14th century, the parts that are millennia old are no longer there so you can only see traces of it in the ground.

Europe on the other hand has impressive structures 2 millenia old like this:
