Dear John,
I’m so glad to know that you are coming to Beijing. It so happens that my brother will be away on business through 18 – 24, so you can stay with us if you like. I’ve made a 5 – day schedule for you: the Great Wall（on 18, Day 1）, Beihai Park and my school（Day 2）, the Summer Palace（Day 3）, the Forbidden City and the Tian’ anmen Square（Day 4）. Nothing special is planned for Day5. You can do some shopping or something else. Please tell me the date of your arrival and your flight number so I can meet you at the airport.
I’m looking forward to seeing you in Beijing.
