:There is no "unknown user" and the red characters were added by a computer program because there were errors in formatting the references. The software recognizes only very specific parameters in the book citation template, and they have to be formatted exactly right. I have made corrections to references 11, 13, 15, 17, 23, 32, 34, 37 and 40. Since I don't read Chinese, please check everything carefully, especially 40 where I had to guess at the name of the work. I have also responded on my talk page. I hope this helps and I apologize for any errors I may have made. English is my only language.
