Dear Sir or Madam,
My name is Li Hua. As an exchange student from China, I am studying in a local school. I am really delighted to learn that a guide for your Chinese cultural relic exhibition is required and I’m confident that I am truly fit for the position.
To start with, my advantage first lies in the fact that I am from China and used to be a volunteer in Shanghai Museum and quite familiar with Chinese relics. Furthermore, being an outgoing and optimistic boy, I am good communicating with others and introducing Chinese culture to the world is always my honor and my pleasure. Finally, there is no problem with my spoken English, as I have lived here for almost a year and I have no difficulty communicating with others in English.
I would really appreciate it if you can offer me the chance to be a volunteer in your museum. I am looking forward to your early reply.
