It is necessary for us to show our plans and arrangements to you. Our plan is to set off next weekend, when the summer vacation officially begins. And, our purpose is to service the Olympic Games. The first stop is Nanjing, the world-renowned city for its beauty and mild temperature. We’ll get there by train and stay there for 2 days, and then we’ll head for Shanghai. After a 3-day stay there, we will give the coaches there a hand so that the game can be held smoothly. As everybody knows, Shanghai is the busiest city in this game, where we will undertake a lot of work, so the stay there will be about half a week. All together, our trip will last about three weeks.

　　Those interested please contact me either through email (xxx@126.com) or phone call (12345678).

　　We are waiting for you sincerely.
