Why is Lu Yu honored as "Cha Sheng"? How did he become the founder of Japanese tea ceremony?

Lu Yu (733~ 804 AD) was born in Jingling, Fuzhou (now Tianmen, Hubei) and was a tea scientist in the Tang Dynasty. He compiled the world's first monograph on tea, Tea Classic, which was praised by later generations as "tea fairy", "Cha Sheng" and "Tea God".

Wang Xianzhi's father is Wang Xizhi, a famous calligrapher in the Eastern Jin Dynasty, and Su Shi's father is Su Xun, an outstanding writer in the Northern Song Dynasty. When these celebrities are mentioned, people will say, "They are all people who won at the starting line at birth." But Lu Yu is an abandoned child in the haystack. On a cold morning in 733 A.D., Master Zhiji of Longgai Temple was walking on the stone bridge in the western suburbs when he suddenly heard a goose singing under the bridge. It turned out that a flock of geese were using their wings to protect an abandoned baby. The feeling of knowing oneself is destined for this child, so I named the child divination, taking Yi as divination: "Hung-chien was born on the ground, and his feathers can be used as tools." So he named it Lu, Yu and Hung-chien.

After writing the Book of Tea, Lu Yu traveled around again. This time, his purpose is not to inspect tea, but to promote tea art. ..

Everywhere I go, I will carry out various activities about tea. Since Lu Yu popularized tea, more and more people drink tea, and the status of tea is getting higher and higher. It can be seen that he promoted the influence of tea art, and at the same time, Lu Yu not only influenced China, but also influenced foreign countries. While tea and tea culture developed in China, tea art also spread to Japan, forming a famous Japanese tea ceremony.
