Dear Teacher Shujingbin
   I’m Sigkharin who’s one of students in your Chinese class. I’m sorry to inform you that I will be absent the Chinese class on this Monday. Because I have to go to my sister’s wedding. And I will go to the class on this Wednesday.
  Ps, I’m so sorry. My English’s not well.
 Yours sincerely,
     Miss Sigkharin Ree-in
