The Book Road According to Chinese researchers, in the first half of the 10th century there already existed a "Book Road" in East Asia, seen in the interchange of Confucian texts, Buddhist scriptures, poetry anthologies, and popular literature on trade routes from China to Japan. This interchange also solidified a common culture that, despite linguistic differences, utilized the same Chinese script.
書之路根據中國學者研究，在西元十世紀前半，東亞就存在著一條「書之路」，從儒家、佛教經典，到詩集、大眾娛樂讀本，都透過這條從中國到日本的交易路線，彼此頻繁地運輸，也建立起「不同語言，卻同樣以漢文書寫」的文化體系。
