Yi Qie Jing Yin Yi written by Xuan Ying of the Tang Dynasty is a model work of the sound and meaning of Buddhist sutras. At present, two collated editions have been published, but there are still many errors that have not been corrected. These errors can be divided into three types: primary errors, secondary version errors and other kinds of errors. Primary errors are annotation errors caused by the limitations of the author’s own knowledge; The secondary version errors refer to the errors added in the spreading of the book. Other kinds of errors are the errors that we can not determine whether they belong to the primary errors or secondary version errors according to the existing materials. Based on this classification, this paper lists several errors that were not reached by predecessors in the previous practice, in order to seek advice from others.
