Ruan Ji
Titles of subsequent sections are either poetic descriptions of tunes, e.g., "Tiger in a Deep Ravine" (3), "Night Demons in a Lonely Wood" (5), and "Snow Geese and Swans Alighting" (7); or references to famous historical whistlers, e.g., "Su Men [Mountains]" (11) was transmitted by Sun Deng, and "The Loose Rhymes of Ruan" was composed by Ruan Ji (both mentioned above). The "Xiaozhi" explains and describes each whistling tune. Take, for example, "Su Men", which retells the story of Sun Deng and Ruan Ji (above), but with whistling instead of zither playing.
