The greatest lasting impact of the Huayan school was to be seen in Korea, where it was transmitted by Uisang (hangul:의상대사 625-702), who had been, along with Fazang, a student of Zhiyan.
He traveled to China, studying at Mount Zhongnan as a student of the influential Huayan master Zhiyan (智儼) and as a senior colleague of Fazang (法藏), with whom he established a lifelong correspondence.
