Dear Leslie,
How are you? I’m writing to tell you about your next Chinese lesson.
We’ll still meet at my school, but not on Saturday as usual, since I’ll have to participate in a sporting activity that day. So let’s make it three o’clock on Sunday afternoon.
As you know, in order to acquire a good knowledge of Chinese, you should learn more about Chinese culture and history. Therefore, this time I will introduce Tang Poetry to you, which is of great help in learning Chinese. I advise you to learn about the brief history of the Tang dynasty in advance. It will surely help you in learning the poems.
Looking forward to hearing from you soon.
Yours,
Li Hua
