Dear Prof. Herthwell,
Many thanks for your kind hospitality and the honor you showed me during our delegation’s recent visit to your university. It was nice of you to introduce me to so many of your famous professors and celebrated scholars at your university. We had a safe and sound trip home. Now we have resumed our work.
Meanwhile, I hope you will someday pay a short visit to our university and give us some lectures on “Modern Western Economics”.
Please have no hesitation in writing to me if you want me to do something for you in China.
With best wishes.
Sincerely
yours,
Li Dong
