Dear Sara,
Nice to hear from you! I really appreciated your phone call at the hotel. I still don't know what precipitated it, but we were happy to have your help with our disappointing room. [The heat was remedied by installing an additional roomkey to keep the fan running in our absence.]
At this time, we don't see another trip to China in our future, but we tell everyone what a great time we had both with your agency, your country, and China's advancement in tourism. We are so grateful that your government has made China's long history and beautiful natural treasures available for the enjoyment of the rest of the world. And we have good reports of the wonderful Chinese people we've met.
Tony, our guide in Xian, is commended for meeting our last minute whim that turned out to be the unexpected delight of the visit to the Huaqing Hot Springs show "The Song of Everlasting Sorrow". Wow! I'm glad I wasn't dissuaded when I was told there wasn't enough to do in Xian to warrant a whole week's visit. We mentioned that we would've also liked to see the Xian Bell Tower performance, and even tour inside the China Post [I recently retired from the US postal service].
Perhaps we can meet you when you come to the United States! Thank you again.
