Album of Miscellaneous Subjects, Leaf 4, 1600s. Leaf 4 This leaf alludes to Wang Wei's poetic lines: In empty hills, there is no one there; Yet one can hear the sound of conversation. Xu Fang's colophon reads: By chance, I start my journey from the watershed to remote regions, Suddenly I see the silhouette of mountains-myriad expanses of green. What is this Feilai Peak which now does not recede? Its rocky walls, linked to heaven, are drenched by a waterfall.
