China's program of language modernization has been as successful as that of any other nation, yet until Chen's book, we have not had a readable and comprehensive discussion of its reforms. Literacy has risen from about 10% in 1949 to around 80% today. Spoken Chinese dialects, from Cantonese through Hakka to Mandarin, vary as much as do the Germanic languages English, German, and Swedish; so it is a major achievement that 90% of Chinese people can now understand Standard Mandarin, up from 40% in the 1950s (p. 8). The current reforms have roots deep in the 19th century, but Chen discusses how early visions of reform became successful only in the past few decades. An unusual virtue of this compact volume is that it discusses language reforms throughout Greater China – not only in the People's Republic, including Hong Kong, but in Taiwan and Singapore as well.
