Dear Mr. and Mrs. Brown,
How is everything going?
We have come back. Thank you for your help during our stay in London. With your help, we had a wonderful time in London. We really have wonderful memories of London:the romantic meals by the river,the Tower Bridge with the Sun setting behind it ,and the world-famous art museums.
With your help, I understand more about UK.For example,the British like to put milk in their tea and it is eompletely different from Chinese tea.Its good to know this.
By the way, how are you doing this day? Thank you for your care and I really want to invite you to visit China and experience the great culture of China.
Yours,
Li Lin
