Dear xxx
  We haven't seen each other for a long time. Recently, I'm staying with my parents in my hometown--Dalian.
  Dalian is a beautiful coastal city in the Northeast of China. It is famous for its seafood and it has the largest city square in Asia. Millions of people come here every year. 
   If you have free time this summer , welcome to my hometown. I will show you around the city and enjoy the beautiful scenery .
