Dear Frank,

As I mentioned before, I would like to write a letter of thanks for all your kindness towards me.
I had only recently arrived in China when I first met you and I really appreciated all the assistance and generosity you showed when we met in Hangzhou Foeign Experts' Meeting last time.

I now have a job and an apartment but I wish our friendship to continue.

Without hesitation, I will introduce you to my friends or anyone I meet who has need of job contacts, travel arrangements and general information.
And I have absolute trust that you will do your best to help them in any way you can with your extensive job, education and travel connrections which are spread all over China.

I would also like to send my best wishes to you and your wife.

Affectionately,
Jonathan
