Dear Tom,
　　I am particularly glad that you are interested in Chinese poetry, geography, nationality and history and eager to explore more.
　　I think the Ancient Poetry is your best choice. By learning Chinese ancient poems, you can have an extensive knowledge of history and culture in ancient China. Also, you can feel the charm of the language by reading poems, which helps to improve your Chinese. To follow the course well, you’d better read and recite as many poems as possible. Besides, it is a good idea to search for related background knowledge so that you will fully understand the concept of poetry.
　　What do you think of the course I am sure you will have a lot of fun from it.
Yours sincerely,
Wang Lin
