Tang ParadiseThe Tang Paradise theme park southeast of Xi'an, which opened in April 2005, occupies 165 acres, 49 of them water. My brother visited there on Wednesday with his fellow teacher, the women hosting them, and the son of one of the women. You can see some of what they saw in the video below.
For more on Tang Paradise, you can read the article on the park that the Boston Globe published in 2006. The photo below of the park's Self-Cooled Pavillion is taken from the Globe article.
