Which city is most worth paying a visit to? Which city is most beautiful?

There are many beautiful cities. Palm Beach, FL is pretty and fun to stay in if you're a tourist. Phoenix, Arizona is a nice place to visit but go in the winter unless you love to walk around in an oven! San Diego, CA is lovely, too, as is El Paso in Texas. My former in-laws visited China a few years ago and were amazed at how beautiful your country is and how nice the people are. They brought me a dragon that they bought from a man atop the Great Wall and it's one of my most treasured dragons. I hope you get to visit all the places that people tell you about!
