Féng Shìlún 馮世綸 (b. 1938) is a contemporary classical-Chinese-medicine scholar in the lineage of Hú Xīshù 胡希恕, known for his revisionist reading of Zhāng Zhòngjǐng’s Shānghán lùn through the lost-formulary substrate. His Zhōngguó Tāngyè jīngfāng 中國湯液經方 (Beijing: Xuéyuàn chūbǎnshè, 2004) argues that the Fǔxíng jué (KR3eh001) preserves the lost Tāngyè jīngfǎ 湯液經法 substrate from which Zhāng drew.
