Dear Xiao Zheng,
I’m very glad to learn that you're going to visit me during the holiday. My parents will also be happy to see you again. I am sure you will enjoy every minute here.
I have arranged our schedule for the holiday as follows. On the first day you arrive, I’ll show you around our campus. On the second day, we'll visit the art gallery and the music hall. Next day, we'll climb a hill in the northeastern part of the city. On the top of the hill, we can have a wonderful bird's eye view of the city. During the next three days, we’ll make some short trips to some places of interest nearby, such as the Swan Cave, the Golden Lake, etc. On the last day, I’ll see you off at the railway station.
Please remember to call and tell me your train number and time of arrival so that I can meet you at the railway station. By the way, it’s very hot here and we have a lot of sunshine, so don’t forget to wear you sunglasses.
I’m looking forward to seeing you soon.
Sincerely yours,
Zhang Tao
