【范文】One possible version：
I’m writing to you from my home in China. I returned home safe and sound. When thinking of the wonderful days I spent in New Orleans, I just can’t help thinking of you. It was so kind of you to have provided everything to make my stay there such a happy experience. I’ve learned so much, not only English but also the culture. And I really enjoyed a great deal, the fun and laughter we shared with each other. Thank you very much. I’ll always remember this trip as well as your kindness.
Welcome to China when it’s convenient for you. I’ll be very glad to show you around. And you’ll surely have a pleasant visit here.
I’ll keep in touch and write to you later. Please take care!
