Thank you for viewing! I purchased this during my student days when I was researching China. I am selling it now as I no longer need it. Would it be useful for research materials? I apologize, but there are traces of lines and such in the text. Please refrain from purchasing if you are concerned. There is also a feature on Carlos Ghosn! If you have any questions, please feel free to comment. I will wrap it in a waterproof bag and pack and ship it via Yu-Yu Mercari delivery, so please rest assured. ^_^ #CarlosGhosn #WeeklyDiamond
