Dear Lin Tao
Thanks for your letter.It's such a surprise to hear of you.I am glad to know that you are going to come my home this summer holiday.Beijing is a beautiful city.The weather in Beijing is sunny and hot.There are lots of places of interest you can visit,such as Tian Anmen Square,the Great Wall,the Summer palace and so on.You'd better take a camera ,wear sunglasses and pack some cool clothes.
Hope to see you soon!
