Yan "class"

This dissertation has detailedly studied Lei Xao(类要), the reference books with arranged materials which compiled by Yanshu (晏殊) , the famous minister of Song Dynasty.The editor had spent most of life to compile the book which came from the course of real reading. So even the 37 volumes remnant of Lei Yao has saved many snippets of rare ancient books that had lost for hundreds years. And many of the materials is important to the research of literature and history. Then the prolegomenon has introduced the most important parts of the book and reviewed the history of utilization and research of the book.The main part is divided into two part, part one is the general research of Lei Yao, which is divided into 3 chapter.Chapter One examines some questions in the course of the compilation, including that the background of the book' s naissance, the time of some parts' compilation, the possible resource of some excerpted documents. The dissertation indicates that culture prosperity of North Song Dynasty and influence of the former reference books with arranged materials caused Lei Yao' s naissance. And according Yanshu' s experience, the part of geography can be considered compiled during 1007-1023. Another point is that because of Yanshu' s experience, some excerpted documents maybe have three resources: royal library, his friends' books and his own collection. In the attached part of this chapter, we examined how did Yanmao (晏袤) , Yanshu' great-grandson, supplement and adapt the original of Lei Yao. We can find that in fact, Yanmao did little thing in adapt the original edition except the part of the geography, and that means most of the edition we can see today has not been changed by other people.Chapter Two particularizes ways of classifying and compilation of former reference books with arranged materials, and according the background, examines the way of classifying and compilation of Lei Yao, finding 73 lost classes of the book and enumerating the special ways of compilation in the book.Chapter three introduces the course of spreading of Lei Yao after its naissance and three editions we can see today. It indicates that before the Yanmao' s edition of 100 volumes was brought into being, the original of Lei Yao had had its influence which was enhanced by Yanmao' s edition. The book spread widely in South Song Dynasty and Yuan Dynasty, in early Ming Dynasty, it went into the royal library and was lost at last before 1605. The two of the three editions was copied in Qing Dynasty, one of which called Shan Ben (陕本) has 37 volumes and another, Bei Da Ben, (北大本)has 16 volumes. Two editions has same content. Most parts ofShan Ben was copied by many copying workers and probably was copied around 1662. 4 volumes of it was copied during 1726—1735. Another point is the far original of Shan Ben is a edition produced in Sorth Song, which was at least once copied until late Ming Dynasty. And the edition produced in late Ming Dynasty direct bring out Shan Ben. In the last the part of the chapter, we have compared Shan Ben and Bei Da Ben, and find that both of them have stupendous mistake, and Bei Da Ben has less. But there are many intended correction in Bei Da Ben, which make it lost original value.Part two examines the lost excerpted documents in Lei Yao. The part is divided into 9 chapter. Every chapter introduces one kind document excerpted in the book and Every chapter is divided into two parts, the forepart is the introduction and the second half is the copy of these lost excerpted documents which didn't be quoted in books earlier than Lei Yao.The attached part one is a list of excerpted documents in Lei Yao.The attached part two is the scraps of Tang Dynasty excerpted in Lei Yao, which was not included in Quan Tang Wen(全唐文)...
