Most manuscripts in China before the early 20th century came from Japan.Therefore,some Japanese scholars think that,the manuscript supposed to be Saicho’s with Kohitsu Ryouchuu’s epilogue among the Dunhuang Manuscrips Collected in Zhejiang Province also came from Japan.By comparing it with Saicho’s works,this paper confirms that it was neither Saicho’s manuscript nor an ancient Japanese manuscript,but a Chinese manuscript of the Tang dynasty.Kohitsu Ryouchuu lived two hundred years ago,and could not have written the epilogue in 1902.The epilogue of its original keeper mentioned nothing about Saicho and Kohitsu Ryouchuu,and this indicates that the original keeper did not see Kohitsu Ryouchuu’s epilogue when he got the manuscript,which might have been added later.
