Dear Tom, 
It is nice to receive your e-mail. Now I'd like to tell you something about the Palace Museum. 
The Palace Museum, also referred to as the Forbidden City,is a fascinating tourist attraction. It dates back to the Ming Dynasty. It was built from 1406 and completed in 1420. As the largest museum in China, the Palace Museum holds precious treasures which have a history of thousands of years. It is said that its temples and palaces amount to 9,999.5.
I do hope you can come to China and take a look at this museum with your own eyes. I'm sure you are more than likely to be attracted.
Yours,
Li Hua
