Dear Leslie,
How are you? Glad to see you have made some progresses in Chinese learning and I'm writing to tell you something about our next lesson.
The lesson will be giving from 3 pm to 5 pm in the afternoon of next Tuesday in the classroom 502. In a class, you will mainly learn Tang Poetry, which reflects traditional Chinese culture and is deep loved by Chinese. You can feel the beauty of Chinese by learn Tang Poetry. You'd better to make full preparations before class and have a brief understanding of the history of Tang Dynasty, which makes easy for you to go through the class.
