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
