Still a hot topic among scholars is discussion of the images about Monk Tang going to the West for Buddhist scriptures and the stories of that Journey to the West. In recent years, a systematic and comprehensive investigation and research on such images in Gansu has been carried out. Information about and images of some wall paintings in previously little known medium or small grottoes has been publicized, creating a larger space for further research. While checking and reading these new materials and the results thereof, the author finds that individual images in Gansu caves seem never to be publicized or recorded. The story painting of the Journey to the West at the Shangshibahe Grottoes is an example. The author had a chance to visit the caves recently, and would like to briefly introduce it here as a supplement.
