Dear 老师,
I know during this coming Chinese New Year, you will not be going home to you hometown in North Pole. You will be alone celebrating the festival. Could I invite you to my house to join my family in out reunion dinner? My family is simple and there are only five members in it. They are my grandparents, my parents and myself.
You acceptance will definitely add atmosphere to this year reunion dinner. We look forward to your reply.

Kind and sincere regards from you student,
