"The Legend of Tea Sage Lu Yu" takes the ups and downs of Lu Yu's life as the "Tea Sage" of the Tang Dynasty as the context, and unfolds a historical picture spanning from the prosperous Tang Dynasty to the mid-Tang Dynasty. Lu Yu, who was born as an abandoned baby, was adopted by Zen Master Zhiji of Longgai Temple. However, he fled the temple because he was unwilling to accept the ancient Buddha of Qingdeng and worked in a theater troupe. By chance, he met Bole and started his studies. He also formed a lifelong friendship with Cui Guofu, who was demoted from an official position, and studied tea ceremony together. During the Anshi Rebellion, he traveled south with the refugees and traveled all over the country to inspect tea ceremonies in various places. In his later years, he lived in seclusion by the Tiao River and spent nearly thirty years writing the masterpiece "The Book of Tea", which systematically summarized tea knowledge and created a new era of Chinese tea culture. Faced with two calls from the imperial court, he stuck to his will and declined the official position, and ended up living in the mountains and rivers. This work is not only a history of personal struggle, but also a hymn about perseverance and original intention. In the fragrance of tea, it witnesses how a legendary figure turned his humble background into an immortal legend.
