Sun Deng
Two "Xiaozhi" sections describe whistling tunes attributed to Sun Deng and Ruan Ji, "Sumen Mountain" (11) and "The Loose Rhymes of Ruan" (13). "Sumen [Mountain]" 蘇門 retells the story of Ruan Ji visiting Sun Deng, referred to as the Daoist master living on Sumen, like the "Shishuo xinyu" above.
