Dear ****,

Working on proofreading the pdf file, a new idea about chapter heading pages occurred to me. All of them seem to hold the same image which is seemingly from some Korean historical literature in the background. It is not bad (but actually boring because there are 36 chapters, which means you have to see the same picture over and over again), but how about giving a word cloud like this: instead? We can show its own word cloud on each chapter. It has nothing to do with any practical purposes, but I simply want the reader to get some fresh air when they enter into a new chapter.
