Pinyin has hitherto been merely a tool for transcribing Chinese characters. It is now becoming also an auxiliary system for writing the Chinese language. Such an extension of its function requires the standardization of its orthography. e.g. rules governing capitalization and the use of open space, hyphens, or closed juncture between syllables. This book is an indispensable tool for understanding the officially approved rules of Pinyin orthography Hanyu pinyin is an extremely important tool. Therefore this scholarly work on Hanyu pinyin and its orthography will make an important contribution to the teaching of Chinese as a foreign language. This contribution is not transitory, but longstanding ... This is a work which possesses both practical significance and scholarly value.
