The Record of the Transmission of the Lamp is an early popular Chan Buddhism lamp record written by Daoyuan, a Buddhist monk of the Fayen Sect. There were three pieces of Xixia accordion-binding manuscript of The Record of the Transmission of the Lamp, numbered Ф. 229B, Ф． 241B and K. K. ll. 0238（K）（British collection） in the documents preserved in Heishuicheng. They are the same scripture unearthed from the same place but collected and preserved respectively in Russia and Great Britain. This paper analyzes the time for The Record of the Transmission of the Lamp to be preserved in Heishuicheng collection, the different versions, and the time for the scripture to be introduced into Xixia. The Record of the Transmission of the Lamp got into Heishuicheng collection, with a unit title, in the fourth year of the Dazhong Xiangfu Period in the Song Dynasty（AD 1011）, while the Xixia manuscripts, with no unit title, are private copies.
