There weren't many tourists, and the two museums were excellent, highly recommended. The ruins park only has some rammed earth platforms left, so it's worth a quick tour. If you're going to visit the ruins park, you absolutely have to buy a tour bus; it's so large you'll either tire yourself out or get sunburned. I recommend standing on the Hanyuan Temple ruins to experience the world's center, roughly 1,300 to 1,000 years ago, right under your feet. It feels like a dialogue between time and space!
