This is the first comprehensive study of Chinese phonology. It covers several areas that were previously thought to be either absent in Chinese, or not phonological issues, e. g. stress, the definition of the word, the word length problem, and the word order problem. It also offers new analyses of several traditional topics, such as the phonemic inventory, allophonic variation, syllable structure, the [r] suffix, tone, and Tone 3 Sandhi. Unnecessary jargon is avoided and relevant theories are introduced in a non-technical way, so that the contents are accessible to a broader audience.
