Most of these texts about the "Erya" were still extant in the Tang dynasty (618-907) but had disappeared by the Song dynasty (960-1279), when there was a revival of interest in the "Erya" (Needham 1986: 192). The Northern Song dynasty scholar Xing Bing () wrote the (c. 1000) "Erya shu" (, ""Erya" Subcommentary"), which quoted many descriptions from both ordinary literature and medicinal "bencao" (, "pharmacopoeia; herbal") texts. A century later, Lu Dian () wrote the (1096) "Piya" ("Increased ya") and the (1099) "Erya Xinyi" ( "New Interpretations of the "Erya"") commentary. The Southern Song dynasty scholar Luo Yuan () subsequently wrote the (1174) "Eryayi" (, "Wings to the "Erya"") interpretation. During the Qing Dynasty, Shao Jinhan (, 1743–1796) published the "Erya Zhengyi" (, "Correct Meanings of the "Erya"") and the naturalist Hao Yixing (郝懿行}}) wrote the (1808-1822) "Erya yishu" (, "Subcommentary on Meanings of the "Erya"").
