Dear Jonathan:

I am more than delighted to invite you to join us to celebrate the Summer Gala--the Olympic Games in Beijing which is considered as the most important occasion for Chinese people. Because of its incomparable status, people carry out a variety of activities across the country to wait for the significant moment.

As we know, the Olympic Games are held every four years in a different city in the world. Athletes from different countries compete in a variety of sports which are composed of both winter and summer games. It was not until 1896 that the first Olympics of modern times were held in Athens. From then on the games are held every four years on a regular basis. As is well known, the Olympics have become the world's most important athletic events and a symbol of friendship of all the people around the world.

At the same time, I do hope all of you will enjoy yourselves during this trip. The first spot you can visit is the Great Wall in Beijing, the grandest fortification in ancient China. The next sight to look around is the Ming Tombs, which are the best-preserved tombs for 13 emperors in Ming Dynasty more than one thousand years ago. In the afternoon, we will go to the Summer Palace, the royal park for Chinese ancient emperors, and then you can go to the Great Wall, which was constructed by respective states for fortifying against invasion of neighboring states. Owing to the long history and its length, it has become one of the eight wonders in the world and represents the highest wisdom and crafts. From the top of the Great Wall, we can enjoy a magnificent view of continuous mountains, green trees and blooming wild flowers. It is no doubt that one says, "He who has never been to the Great Wall is not a true man".

I am convinced that your trip to Beijing in the coming August will be to your heart's content. And I'm looking forward to seeing you in Beijing.

Sincerely yours,
　　Zhou Ming
