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 is also called the Forbidden City．It took 200，000 workers more than 13 years to build the Forbidden City．The Forbidden City was finished being built in 1420．The largest museum in the world，the Palace Museum，holds cultural treasures from the past 5，000 years of Chinese history．The city's palaces have 9，999 rooms altogether．Chinese people traditionally have thought of nine as a lucky number．Students from all over China now visit in groups at no charge every Tuesday．
I hope you can come to China and take a look at this museum with your own eyes．
Best wishes．
Yours，
Li Ming
