Dear Mr.Jackson:
First of all,i would like to thank you for your care and hospitality during my visit to the university in Hong Kong.My visit couldn't have been better without you.
The university was bigger than i thought it would have been,i would probably get lost if it wasn't for you.It was a great pleasure meeting the principal,the students and other professors.Thank you so much for introducing me to them,i am looking forward to meet them again.
Words are still unable to describe and convey my appreciation.
Once again,i just want to thank you for everything.
Sincerely,
XXXXX
