April 10 Dear Mr. and Mrs. Brown, I'm writing to you from my home in China. So glad that I could live in your lovely home when I studied in New Orleans for a whole year. You provided me for a beautiful room, and we ate together. I also never forgot you accompany for my study life. I am very happy you could come to my home in China when you are available. I am hoping we can always keep in touch with each other, and I will share my more story in China with you. Looking forward to your reply.
