Dear Luo Lin，
I’m writing to express my thanks to you and your parents for your great kindness and help during my stay at your home while in China to join in the Chinese Bridge activities.It was a very good time that I’ll never forget.Besides，your beautiful campus as well as the students’ high spirits in study are also deeply impressed in my memory.Can you tell me why you work so hard at your lessons？And how do you usually relax yourselves after study?
Welcome to my home in Washington  State some day.
Give my best regards to your parents!
Affectionately yours，
Catherine
