In your last letter, you mentioned that you would pay a visit to Beijing in order to learn Chinese.Thus, to help you learn Chinese better, I'd like to introduce a book called the idioms in Chinese during a conversion, which is rather suitable for you.Costing 15 yuan, it really has a reasonable price.Besides, the definitions of the idioms are not only accurate but also complete,fitting it for a beginner. What's more, once buying it, you can also get some Cassettes, which is absolutely considerate for self teaching learners. The book is always available on the Internet.
