Ruan Ji
Ruan wrote philosophical essays about the "Yijing", "Daodejing", and "Zhuangzi", his masterful "Yonghuai shi" "Songs of My Soul", and "Yue lun" "Disquisition on Music". Among recluse poets who practiced transcendental whistling as a way to absorb themselves into nature, Ruan Ji was the most famous whistler of the Jin dynasty. After meeting Sun Deng, Ruan Ji immortalized him in "Daren xiansheng zhuan" "Biography of Master Great Man", which praises Daoist transcendence over the mundane world.
