Regarding Song Meiling's Memoirs of the Xi'an Incident, we learned from the book that the writing of the manuscript began in early 1937. When Song started writing this article, he intended to sell it to the highest bidder and set up a fund to educate the orphans of the guards killed in the Xi'an Incident. The highest bidder was Aban. On behalf of the North American Newspaper Federation, he bought the copyright of the book from Song Meiling for 12,000 US dollars and published it in North America. Song Meiling's original manuscript is in English. The Chinese version we read today is the translation of the English version purchased by Aban.
