Cao Kun
In the fourth impression, published in December 1934 by Victor Gollancz Ltd., additional information such as the fully spread fan (pp. 448–9) was developed and some important parts of the history, such as the confinement of Cao Kun (p. 381) and Kang Youwei's escape from the country (p. 17), were reviewed for modification with "preface to the fourth impression" (p. 6) (Japanese translation; ).
