22.2 invite

Dear friends, 
  I am a colleage student majoring in computer science.I am writing for the purpose of telling you about my plan for a tour of a historical site.

  There are many historical sites in China,from my perspective,I think the best place to visit is the Great Wall.The Great Wall is not only the largest structure in the world,but also has a long history.Finally,it is essential to mention that you should make an appointment in advance and bring your ID card.I do hope that my plan will be beneficial for you.

  thank you for taking up your time to read.I look forward to your favourable reply at your earliest convenience if further information is required.
  Yours sincerely,
  Li Ming
