The Study Of Cao Yun Tong Zhi

The Cao Yun Tong Zhi is a professional record of the water transportation of grain in the Ming Dynasty.It was compiled by Yang Hong,a scholar from Ming Dynasty.Because of inviting a famous learned man who named Xie Chun to revise,some contemporary books then regard him as the writer.Because of Yang Hong's leading role and important efforts in the process of writing,this view is unreasonable.The original title of the paper is named“Cao Yun Zhi”,influenced by the name and content of the preface,the literature of the same name,re-publishing and so on,it was changed to“Cao Yun Tong Zhi”about between 1543 and 1555.There is a complicated background in the writing of The Cao Yun Tong Zhi.The changing policy of transportation of grain in the early Ming Dynasty,the rise of books about canals,the inefficient policy of transportation in the end of reign of the emperor called Ming Wu Zong,and the new political plan in the early days of rule by the emperor called Ming Shi Zong provide the opportunity and conditions for the book to be completed.According to the analysis,the source of the material mainly includes the official documents,the relevant canal essay,the inscriptions,and ancient books,such as Tong Dian.Because Cao Yun Tong zhi constructs the article system in the form of "graph","table","excerpts",regards the transportation of grain in Ming dynasty as the subject of description,and therefore compared with similar works,it presents rich content,diverse forms of expression,brief ancient describe,abundant modern describe and other characteristics.The records of Cao Yun Tong zhi is rich,true and reliable,so it not only has an important value of historical materials but also an important documentary value.The value of historical materials is reflected in the preservation of data in the fields of transportation,taxation and water Conservancy technology,while the documentary value is reflected in the inadequacy of supplementing other documents,proofreading other documents and providing reference for other documents.
