Zhiyan
Zhiyan (Chinese: 智儼; pinyin: Zhìyǎn) (602–668) was a prominent monk of the Tang dynasty who is considered the second patriarch of the Chinese Buddhist Huayan school. He was a disciple of the foundational figure Dushun (杜順) and later became the mentor to both Fazang (法藏), who systematized Huayan doctrines, and the Korean monk Uisang (義湘). During his lifetime, Zhiyan was often referred to by honorific titles such as “Master Zhixiang” (至相大師) and “The Venerable of Yunhua” (雲華尊者).
