Dear Li Ming,
I'm sorry to tell you that I can't celebrate the Christmas with you and your families, because I have just recieve my parents request that I should take a plane on December 12th and fly back to Switzerland to spend the Christmas with them.
I really appreciate for your families warmly welcome and your help during my study in China. I am fond of the life here, especially the activities held by the cycling group from our institute. I hope that all of your family can come to Switzerland for vacations one day. If you come, please connect me with John＠hotmail.com. I will be very glad for your coming.
Best wishes!
Yours,
Jhon
