Dear Cathy,

Hello! Thank you for your help and good treat while we were traveling in London. You were so kind and friendly to treat us with good meals, and show us around the city. It is really nice to visit London, whose beautiful scenery and delicious food gave me a good impression. I had a great time there and learned a lot about London. Cathy, are you free these days? I would like to invite you to visit China. I"ll show you around the interesting places, such as Beijing and Xi"an.

Looking forward to your reply.

Best regards

Yours,
