Dear Tom,
I'd like to invite you to visit my hometown—Nanjing. The air here is fresh and people here are friendly.
There is a beautiful park called Xuanwu Lake Park. We can walk or go jogging there.The Sun Yat-sen Mausoleum and the Nanjing Yangtze River Bridge are very famous. I want to show you around the places.
I live with my parents in a new flat in the city centre. You can live with us.
Welcome to my hometown. I'm looking forward to meeting you soon.
Yours,
Mike
