Shenzhen city, Guangdong province, China you should go to Huaqiang North, World Window, Xiangmihu Resort, Beach, etc
I have never been to Costa Rica. My cousin works in San Jose, he loves it there, in fact I have a place to stay down there but, I was thinking about going places that are more interesting.
I have traveled the world and have seen many wonderful places but none compare to the northern California coast, and make sure you get to the Redwood Forest.
