Dear my colleague:
I have come over home.It is really a nice thing writing to you with pleasant memories together with you in America.
Firstly,I want to express my thanks for your warm reception.You taught me English.Took me everywhere to enjoy beautiful scenes and talked about cultures of your country to me,which all benefits me a lot.
Then,I hope you can visit China next month.I have been established for it.I believe that it would be a surprise to you and we can discuss Chinese culture with enjoyable Chinese scene.
I hope you will take my suggestion into account.Hope for seeing you in China.
Yours
