[Study on the title of Chongbian Yijingxiaoxue]

Chongbian Yijingxiaoxue was compiled by Jitian Zongxun in 1590 - 1610. The existing editions included a carved edition and copied edition, then came the photocopy. There was a chapter entitled 'Loujing Xuefa' which recorded 29 extrameridian points. This chapter was compiled into a verse in Volume 3 of Chongbian Yijingxiaoxue. As the book had always been confused with Yijing Xiaoxue, written by Liu Chun in the Ming Dynasty, its literature value increased and became necessary in literature research on extrameridian points. This kind of error was related to people's credulity and blindness on the authority of classical books and 'momentum of literature error'.
