Shanghai Girls takes place between 1937 and 1957. Readers will find some of what today we would call politically incorrect terms, but they are accurate to the time. I have used the Wade-Giles system of transliteration for Chinese words-whether in Mandarin, Cantonese, or in the Sze Yup and Wu dialects-again in keeping with the era.
Regarding exchange rates: Silver dollars were used in Shanghai before November 1935; Chinese yuan were used after 1935. The two were roughly equivalent. I have chosen to stay with dollars and cents because some were still in circulation and they are a more familiar currency to Western readers. The copper-silver exchange rate ranged from 300 to 330 coppers for every silver dollar (or yuan).
