This book documents in detail the complex relationships between Simplified Chinese and Traditional Chinese: the two forms of 7000 characters matched up, complex cases annotated with the word contexts in an innovative layout. It is a specialized dictionary, primarily intended for answering a common question: given a Chinese character, either Simplified or Traditional, what is its counterpart in the other form? For everyone reading, writing and converting the two written forms of Chinese, it is an essential reference; for those who are proficient in one of the two forms, it provides a self-study path to master the other form; and for anyone who is interested in understanding the two written forms, it is an one-stop resource on the subject.
