I have been in contact with Beijing Tongzhi (by email) since 2009. 张永宁, producer of the film Lan Yu, is the person who put me in touch with the author. Early in our correspondence, Beijing Tongzhi gave me permission to translate and publish the book. I do know some things about the author’s personal identity and whereabouts, but have promised the author that I will not make any of this information public. I do not know why Beijing Tongzhi has chosen to keep his or her identity a secret, but it’s the author’s choice and I respect it.
