Dear Mike,
How are you doing recently?I hope you are doing great.
It is so kind of you to send me an English dictionary as my birthday present.Thank you so much and I really like it.I always have some trouble on English spelling,and this dictionary is just what I need at present.It will be of great help to improve my spelling abilities.
I am also grateful for the birthday card you sent me.I look forward to meeting you in China next month,and I would like to invite you to lodge with my family at the time.Please let me know your response.Wish you a healthy and prosperous life.
