颜真卿
According to tea lore, Lu Yu was an orphan of Jinling county (now Tianmen City in Hubei Province) who was adopted by a Buddhist monk of the Dragon Cloud Monastery. He refused to take up the monastic robes and was assigned menial jobs by his stepfather. Lu Yu ran away and joined the circus as a clown. At age 14, Lu Yu was discovered by the local governor Li Qiwu, who offered Lu Yu the use of his library and the opportunity to study with a teacher. During the An Lushan and Shi Siming rebellion period, Lu Yu retired to Shaoqi (now Wuxing county, Zhejiang). Lu Yu made friends with many literati, including the calligrapher Yan Zhenqing and the poet Huangfu Zheng.
