假如你是李华,你的美国朋友Sam这学期打算选修学校新开设的中文选修课.请你根据以下要点提示给他写一封信.

Hi Sam,
Hope you are doing well! I heard that your are taking the new Chinese elective course opened by your school this semester. I am very glad that you decided to learn Chinese. I can guarantee you that it's a language worth learning. Just imagine what you can do with it! I can show you around all the beautifal sceneries in China and introduce you to my Chinese friends. I am always here for you in case you need any help. Please let me know if you have any questions regarding grammars, pronounciations, or you just need someone to practice Chinese with.
Best luck in your language learning and I am looking forward to your reply.
Sincerely,
Li Hua
