One possible version：
I’m glad to hear that you will come to Beijing to study. It's a big surprise for me and I'm looking forward to seeing you earlier.
Located in the north part of China, Beijing is the capital of our country. It is hot and rainy in summer but cold and dry in winter. It is a big city with many tourist attractions, such as the great Wall, the Summer Palace and the Forbidden City. Would you mind telling me when you will arrive in Beijing? I will pick you up at the airport and show you around those beautiful places.
