Dear Uncle Bob,
I'm so glad to hear from you about visiting Beijing.Here's the trip plan. We'll meet at the airport at 2 p.m. on June 30th. We can go to the hotel directly to have a rest as I've already booked the rooms. The next day we'll watch the flag-raising ceremony at Tian'anmen Square early in the morning. It must be amazing! What about the Great Wall? It's worth visiting and you'll be impressed. As for dinner, we'll have the delicious food, Beijing duck. Honestly,I am getting excited about the trip.
Look forward to meeting all of you in Beijing.
