Dear David,
I’ve just got back home. I want to say thanks to you and your family because you took good care of me during my stay in the UK. You were patient enough to help me with my English. You showed me around London. Your mother sent me to hospital when I felt sick and cooked delicious food for me. Now, I have improved my English and learnt more about British culture. I would like to invite you and your family to my home. I will cook Chinese food for you. I’m sure you can have a good time visiting China.
Yours,
Li Hua
