Dear Suran,
Xiaoming's birthday is coming. We would like to have a party for him. And we would like to invite you to come to the party, too. The party will be from 8 o'clock to 9 o'clock on Friday in the students' club. We will have a birthday song, cake for Xiaoming. And there will be games then. The only request is that you would have to prepare a gift for Xiaoming.
We're looking forward to your coming.
Yours Sincerely,
Li Hua
